▼ Superconductivity presents itself many peculiar and interesting properties in different dimensionalities, which have attracted much attention ever since it has been discovered in bulk materials. At an early stage, theoretical models were established in 3D regimes to describe the conventional bulk superconductivity, while superconductivity was also gradually observed and well studied in 2D, 1D and 0D materials, both experimentally and theoretically. Nevertheless, new superconducting materials are emerging regularly, with novel phenomena, unknown mechanisms and the potential to future applications. This makes superconductivity so charming that people never let up the efforts to further excavate and explore the mystery of superconductors. In this thesis work, I will investigate superconductivity in several materials, including a Nb doped bulk topological insulator (Nb_xBi₂Se₃), 2D interfacial superconductor (Bi₂Te₃/Fe_1+yTe) and 1D nanowires (Sn and Al). The basic concepts of superconductivity and corresponding microscopic theories will be introduced in Chapter 1, including the London equation, the Ginzburg-Landau theory and the Bardeen-Cooper-Schrieffer (BCS) theory. Especially, the BCS theory is applicable to conventional superconductors, of which electrons can be weakly bonded as Cooper pairs and move without any resistance below the superconducting transition temperature T_c. However, in low dimensionality, thermal fluctuation activated phase slips of the order parameter will be enhanced and result in a finite resistance in 1D or 2D materials below T_c. For 1D superconductors, such a process has been well explained by the Langer-Ambegaokar-McCumber-Halperin (LAMH) theory. For 2D superconducting materials (thin films or Josephson junctions), vortex-antivortex bonded pairs can form a quasi-long-range-ordered phase coherent state in the 2D plane below a characteristic temperature T_BKT, which is slightly lower than T_c. Therefore, a zero resistance state could also be established in 2D films or Josephson junctions, which fall in the same universality class, and such a transition is described by the well-known Berezinskii-Kosterlitz-Thouless (BKT) theory. Various instruments and methods have been involved in this thesis work, which will be briefly described in Chapter 2. Mainly, I focus on the transportation properties and magnetization investigations, and one of my frequently used techniques, the point-contact spectroscopy, will be thoroughly discussed with the corresponding theoretical model, the Blonder-Tinkham-Klapwijk (BTK) model, being presented. In the following Chapter 3, a study of the upper critical field transition in Nb doped Bi₂Se₃ by field-angle-resolved resistive and magnetization measurements will be presented. 3D topological insulators (TI) could become superconducting by doping with intercalation of metallic ions, such as Cu_xBi₂Se₃,…

▼ This dissertation is centered on investigation of metastable thermoelectric thin film materials and is split into 3 primary sections. Section 1 focuses on formation mechanisms of FeSbx compounds from layered precursors. It was found that a compositionally favorable and homogeneous nucleation environment allowed for the nucleation of a metastable phase, which surprisingly resembles the local coordination environment of the precursors, even in cases where they are compositionally unfavorable. Over the course of this work, the technique of normal-incidence thin film pair distribution function analysis is introduced, which allows for rapid acquisition and analysis of local structure data from intact thin films. Section 2 investigates changes in the stacking sequences of ([PbSe]1+δ)m(TiSe2)n nanolaminate materials, which consist of interleaved layers of each compound in the chemical formula, and how these changes effect the thermoelectric power factor. Homologous series of systematically varying m and n values are investigated and measured properties are correlated back to the designed nanoarchitecture of the laminate materials. It is found that the compounds are stabilized by electron exchange between constituents at the interfaces, and that ‘doping’ of the laminate structure by changing the relative amounts of each constituent is an effective means of optimizing their transport properties. It is also shown that interface density between constituents can be utilized to optimize performance. Section 3 moves from the case of PbSe layers, which maintain their structure, to SnSe layers that significantly distort as the layer size is changed. The distortions in SnSe are observed to occur from templating off TiSe2 layers. As the size of the SnSe layers increases, relatively fewer templated interfacial atoms exist and stabilization of interior atoms must also be considered. The coarse behaviors developed in ([PbSe]1+δ)m(TiSe2)n hold, but the structural distortions in SnSe likely change the band structure of this constituent and hence the composite material, complicating the analysis. In some cases, these changes allow for radically different behavior, best exemplified with high TiSe2 ratios in ([SnSe]1+δ)1(TiSe2)n displaying significant enhancement of the Seebeck coefficient at cryogenic temperatures over the low-n and PbSe-containing analogues. This dissertation includes previously published and unpublished coauthored material. Advisors/Committee Members: Johnson, David (advisor).

▼ The modern world's dependency on electronics provides a constant need to discover new materials and devices. A promising technique to fabricate a new device is to create a heterostructure; a device consisting of two bulk crystals joined at an interface. These materials often support a low dimensional electron gas confined to the interface, which exhibits properties different than both the parent materials. These materials have led to the creation of MOSfets, the discovery of the quantum Hall effect, and in recent years the discovery of Majorana edge modes in nanowires. In this thesis, we study several different heterostructures. We begin with one of the most famous heterostructures, AlGaAs/GaAs. Modern AlGaAs/GaAs heterostructures support a high mobility two-dimensional electron gas (2DEG) in a quantum well. The 2DEG is provided by two remote donor δ-layers placed on both sides of the well. Each δ-layer is located in the midplane of a narrow GaAs well, flanked by narrow AlAs layers which capture excess electrons from donors. We show that each excess electron is localized in a compact dipole atom with the nearest donor. The excess electrons screen both the remote donors and background impurities, and are responsible for the observed high mobility. Still, we find that the mobility is substantially lower than theoretical estimates, which may be due to significant disorder in the donor layers, most likely roughness of the interfaces or spreading of the donors out of the midplane of the layer. Thus one should take care to make sure that the donor layers are as ideal as possible. We next move on to oxide heterostructures involving SrTiO₃ (STO). More specifically, we study the electron gas in accumulation layers of these heterostructures characterized by a density profile n(x), where x is the distance from the STO surface. SrTiO₃ at liquid helium temperatures has the highest dielectric constant which strongly enhances the role of nonlinear dielectric effects. It was recently shown that the nonlinear dielectric response results in an electron density profile n(x) that slowly decays as 1/x^12/7. We show that such a long tail of n(x) causes the magnetization and the specific heat of the accumulation layer to diverge at large x. We explore the truncation of the tail by the finite sample width W, the transition from the nonlinear to linear dielectric response with dielectric constant κ, and the use of a back gate with a negative voltage -\abs{V}. We find that as a result both the magnetization and specific heat are anomalously large and obey nontrivial power law dependences on W, κ, or \abs{V}. In the linear dielectric regime under a strong magnetic field, the large dielectric constant of STO makes it easy to reach a quasi-one-dimensional state known as the extreme quantum limit (EQL) in which all electrons occupy the lowest Landau level. We present a theory of the EQL phase in STO accumulation layers. We find a phase diagram of the electron gas in the plane of the…

▼ Semiconductor heterostructures provide an exciting setting for novel electronic and optoelectronic devices. Energy band alignment in semiconductor heterostructures is one of the most important parameters of design since it controls the electrical and optical properties. Extensive library of two-dimensional (2D) semiconductors allow us to create a wide range of heterostructures made by stacking different 2D semiconductors on top of each other, held by van der Waals forces.In this thesis we employ state-of-the-art first-principles calculations based on density functional theory (DFT) to investigate energy band alignments in two-dimensional (2D) semiconductor heterostructures. The Anderson and midgap models are often used in the study of semiconductor heterojunctions, but for van der Waals (vdW) vertical heterostructures they have shown only very limited success. Using the group-IV monochalcogenides as a prototypical system, we propose a linear response model and compare the effectiveness of these models in predicting DFT band alignments, band types and bandgaps. We show that the true band alignment can be obtained by the linear response model, which falls in between the Anderson and midgap models. Our proposed model can be characterized by an interface dipole eV_h = α × (E_m2-E_m1), where the linear response coefficient α = 0 and 1 corresponds to the Anderson and midgap model respectively, and E_m is the midgap energy of the monolayer which can be viewed as an effective electronegativity. For group-IV monochalcogenides, we show that α = 0.34 best captures the DFT band alignment of the vdW heterostructure, and we discuss the viability of the linear response model considering other effects such as strains and band hybridization. Topological insulator has been touted as a very promising class of material for spintronics applications. A particular property of interest is its intrinsic spin-momentum locking protected by time reversal symmetry. However, in current state-of-the-art molecular beam epitaxial grown materials, various defects has been observed. Here we investigate effects of rotational defects and basal twins on electronic properties of topological insulators (TI) such as Bi₂Te₃, Bi₂Se₃, and Sb₂Te₃. We demonstrate that basal twins and defects affect the local band structure of the TI thin films. However, it’s most important feature remains relatively robust, i.e. the important 90⁰ spin-momentum locking of the surface states. Finally, we study MgV₂O₄ as a promising and chemical material for spintronics applications, due to its excellent lattice matching with MgO. We show that the ferromagnetic (FM) phase of this material is half-metallic, and its half-metallicity is preserved even after interfacing with MgO, as we validate through their heterostructure calculations. Interestingly, we also show that the FM phase of spinel compound MgV₂O₄ host three-dimensional flat band (FB) right near the Fermi level, consequently yielding a large…

O supercondutor (SC) YBa2Cu3O7 (YBCO) foi descoberto em 1986, e desde então tem sido amplamente estudado em suas diversas formas e propriedades. Dentre suas várias características, sua alta temperatura crítica é uma das mais importantes na ciência e na tecnologia. Atualmente existem vários dispositivos baseados no YBCO. As heteroestruturas do tipo SC/FM, onde FM representa uma camada ferromagnética, criadas nas últimas décadas, constituem uma das mais interessantes formas de aplicação deste material. Estas são altamente promissoras para o desenvolvimento de dispositivos spintrônicos que exploram as propriedades dos spins dos elétrons. Neste trabalho o foco foi estudar os efeitos das interações entre a camada de YBCO e a do ferromagneto La2/3Ca1/3MnO3 em super-redes intermediadas por camadas de diferentes espessuras de determinados materiais isolantes. Os materiais isolantes testados foram o SrTiO3 (STO), o CeO3 e o PrBa2Cu3O. As super-redes foram fabricadas pela técnica PLD com parâmetros optimizados. Algumas das características foram determinadas por meio de medidas de DRX, MEV, EDS, de magnetização e de transporte. Estruturalmente, as super-redes apresentaram integridade de composição e cristalinidade com crescimento preferencial na direção c. As imagens de MEV confirmaram o crescimento apitaxial das camadas, e o EDS sua composição. As medidas de magnetização mostraram o grau de qualidade e o comportamento da super-rede que resulta da interação ou desacoplamento eletrônico das camadas SC e FM quando uma camada isolante é inserida entre elas. A mesma análise foi feita nas medidas de transporte. As super-redes (YBCO20nm/ISOdl/LCMO10nm)x20 apresentaram comportamento predominantemente supercondutor. Enquanto as super-redes (YBCO20nm/ISOdl/LCMO20nm)x20 apresentaram oscilações das temperaturas crítica e de Curie assim como magnetização e resistividade não usuais dependendo do isolante e de sua espessura...

The superconducting (SC) YBa2Cu3O7 (YBCO) was discovered in 1986, and since than it has been widely studied in its various forms and properties. Among its many features, its high critical temperature is one of the most important in science and technology fields. Currently there are several devices based on YBCO. The SC/FM heterostructures, where FM is a ferromagnetic layer, created in recent decades, is one of the most interesting ways of applying this material. These are highly promising for the development of spintronic devices exploding the properties of electron spins. In this work the focus was to study the effects of interactions between the YBCO layer and the ferromagnet La2/3Ca1/3MnO3 in superlattices mediated by layers of differente thicknesses of certain insulating materials. The tested insulating material were SrTiO3 (STO), CeO2 and PrBa2Cu3O6. The…

▼ Thermal transport across three-dimensional Lennard-Jones superlattices, two-dimensional heterostructures of graphene and hexagonal boron nitride (hBN), and in C60 molecular crystals is studied atomistically. The first two systems are studied as finite junctions placed between bulk leads, while the molecular crystal is studied as a bulk. Two computational methods are used: molecular dynamics (MD) simulations and harmonic lattice dynamics calculations in conjunction with the scattering boundary method (SBM). In Lennard-Jones superlattice junctions with a superlattice period of four atomic monolayers at low temperatures, those with mass-mismatched leads have a greater thermal conductance than those with mass-matched leads. We attribute this lead effect to interference between and the ballistic transport of emergent junction vibrational modes. The lead effect diminishes when the temperature is increased, when the superlattice period is increased, and when interfacial disorder is introduced, and is reversed in the harmonic limit. In graphene-hBN heterostructure junctions, the thermal conductance is dominated by acoustic phonon modes near the Brillouin zone center that have high group velocity, population, and transmission coefficient. Out-of-plane modes make their most significant contributions at low frequencies, whereas in-plane modes contribute across the frequency spectrum. Finite-length superlattice junctions between graphene and hBN leads have a lower thermal conductance than comparable junctions between two graphene leads due to lack of transmission in the hBN phonon band gap. The thermal conductances of bilayer systems differ by less that 10% from their single-layer counterparts on a per area basis, in contrast to the strong thermal conductivity reduction when moving to from single- to multi-layer graphene. We model C60 molecules using the polymer consistent force-field and compute the single molecule vibrational spectrum and heat capacity. In the face-center cubic C60 molecular crystal at a temperature of 300 K, we find three frequency peaks in the center-of-mass translations at 20, 30 and 38 cm􀀀1, agreeing with the average frequencies of the three acoustic branches of the frozen phonon model of the same system and suggesting that a phonon description of center-of-mass translations. We use both direct method and Green- Kubo MD simulations to predict the thermal conductivity of the molecular crystals at a temperature of 300 K. We find that the thermal conductivity of the molecular crystal is 20 to 50% lower than that of a reduced order model where only molecular center-ofmass translations are present, suggesting that molecular vibrations and rotations act as significant scattering sources for the center-of-mass phonons.

▼ Current and future technological needs increasingly motivate the intensive scientific research of the properties of materials at the nano-scale. One of the most important domains in this respect at present concerns nano-electronics and its diverse applications. The great interest in this domain arises from the potential reduction of the size of the circuit components, maintaining their quality and functionality, and aiming at greater efficiency, economy, and storage characteristics for the corresponding physical devices. The aim of this thesis is to present a contribution to the analysis of the electronic charge and spin transport phenomena that occur at the quantum level in nano-structures. This thesis spans the areas of quantum transport theory through time-dependent systems, electron-boson interacting systems and systems of interest to spintronics. A common thread in the thesis is to develop the theoretical foundations and computational algorithms to numerically simulate such systems. In order to optimize the numerical calculations I resort to different techniques (such as graph theory in finding inverse of a sparse matrix, adaptive grids for integrations and programming languages ({\it e.g.,} MATLAB and C++) and distributed computing tools (MPI, CUDA). Outline of the Thesis: After giving an introduction to the topics covered in this thesis in Chapter 1, I present the theoretical foundations to the field of non-equilibrium quantum statistics in Chapter 2. The applications of this formalism and the results are covered in the subsequent chapters as follows: Spin and charge quantum pumping in time-dependent systems: Covered in Chapters 3, 4 and 5, this topics was initially motivated by experiments on measuring voltage signal from a magnetic tunnel junction (MTJ) exposed to a microwave radiation in ferromagnetic resonance (FMR) condition. In Chapter 3 we found a possible explanation for the finite voltage signal measured from a tunnel junction consisting of only a single ferromagnet (FM). I show that this could be due to the existence of Rashba spin-orbit coupling (SOC) at the interface of the FM and insulator. Assuming that the measured signals are quantum mechanical effect where a solution to the time dependent Schrodinger equation is required, I use Keldysh Green function formalism to introduce a "multi-photon" approach which takes into account the effects of time-dependent term exactly up to scatterings from a finite number of photons. We then proceed to find the corresponding Green function numerically using a recursive method which allows us to increase the size of the system significantly. We also implement other approximations such as adiabatic and rotating frame approaches and compared them with our approach. In Chapter 4, I investigate the spin and charge pumping from a precessing magnetization attached to the edge of a 2-dimensional topological insulator (2DTI). We show that, in this system a huge spin current (or voltage signal if the FM covers only one edge) can be pumped for very small cone angles of the… Advisors/Committee Members: Nikolic, Branislav.

▼ High-resolution x-ray diffraction is a valuable non-destructive tool for the structural characterization of semiconductor heterostructures, and measured diffraction profiles contain information on the depth profiles of strain, composition, and defect densities in device structures. Much of this information goes untapped because the lack of phase information prevents direct inversion of the diffraction profile. A common practice is to use dynamical simulations in conjunction with a curve-fitting procedure to extract the profiles of strain and composition in the depth of the material. Prior to this work, the dynamical simulations have been based on perfect, dislocation-free laminar crystals, and this renders the analysis inapplicable to many real structures which contain dislocation densities greater than about 10⁶ cm^-2. In this work we present two novel dynamical models for Bragg x-ray diffraction in semiconductor crystals with arbitrary, nonuniform composition, strain, and dislocation density: the Phase Invariant Model for Dynamical Diffraction (PIDDM) and the Mosaic Crystal Model for Dynamical Diffraction (MCDDM), which improves upon the former with greater accuracy and better computation times. The framework for dynamical diffraction calculations is based on the Takagi-Taupin equation, but modified for distorted crystals by accounting for the angular and strain broadening introduced to the lattice by the presence of dislocations. In this thesis we cover dynamical diffraction from perfect crystals then provide a description of both PIDDM and MCDDM models. We present results for each of these using the Si_1-xGe_x / Si (001), ZnS_ySe_1-y / GaAs (001), and In_xGa_1-xAs / GaAs (001) material systems in multilayer, superlattice, step-graded, and linearly-graded heterostructures. We also compare the MCDDM to experimental measurements of an In_xAl_1-xAs / GaAs (001) metamorphic device structure. Lastly we provide a comparison of the two models with In_xGa_1-xAs heterostructures. We show that these two models for defected crystals extend the usefulness of the x-ray diffraction characterization method and should in principle allow depth profiling of dislocation densities in arbitrary heterostructures.

▼ In the last decade or so, layered materials have attracted significant attention due to their promise for tailoring electronic properties at an atomic level. Individually, these materials have exhibited strong attributes, relevant for both electronic and optoelectronic applications. However, the real world implementation of semiconducting materials is often derived from the junctions they form with other semiconductors. Thus, much of the interest in 2D materials arises from exploiting their ability to form low dimensional heterostructures. From a structural stand point, there are two ways these heterostructures can be formed, either vertically or laterally. The more common, vertical heterostructures, are intriguing due to their van der Waals adhesion, which eliminates many of the constraints attributed to lattice matching between materials. Lateral heterostructures, on the other hand, provide the unique opportunity to form in-plane junctions within a 2D sheet, creating novel 1D interfaces. To better understand these various heterostructures, this dissertation aims to explore photocarrier dynamics, using ultrafast laser spectroscopy techniques, in several types of structures yet to be extensively studied. First, charge and energy transfer mechanisms in vertical heterostructures formed between various transition metal dichalcogenide monolayers are studied, highlighting the addition of type-I band alignment to the discussion. Next, the extent to which materials can interact electronically through van der Waals adhesion is explored at the interface between amorphous and crystalline layers. From there, the focus shifts slightly to carrier dynamics across lateral junctions formed within monolayer sheets of transition metal dichalcogenides. This includes a discussion on lateral heterostructures, formed between different materials, as well as homostructures where an electronic junction can be induced in a single material. All of these studies will provide a unique overview on the possible directions and applications for which two dimensional materials can be facilitated. This dissertation includes previously published authored material.

▼ In this thesis we study low dimensional hole systems fabricated on GaAs/AlGaAsheterostructures without any modulation dopants. The electrical transports of holes in twodimensions (2D), one dimension (1D) and zero dimension (0D) are studied. Two types of fieldeffect transistors are fabricated and studied. The first type is a semiconductor insulatorsemiconductor field effect transistor (SISFET) in which 1D hole wires and a hole quantum dotare studied. The second type is a metal insulator semiconductor field effect transistor(MISFET) in which devices with the ability to switch the type of charge carriers in theconduction channel between electrons and holes are fabricated (ambipolar devices).The 1D hole wires are fabricated on the crystal plane of (100). The 1D hole wires showstrong Zeeman splitting when the in-plane magnetic field is applied parallel to the 1D wires,and very small Zeeman splitting when the in-plane magnetic field is applied perpendicular tothe 1D wires, regardless of the crystallographic orientation ([ 011] or [011 ̅] ). This effect isdifferent compared to 1D hole wires fabricated on the crystal plane of (311)A, where there isan interplay between anisotropies due to the low crystal symmetry and 1D confinementresulting in different Zeeman splitting measured in wires oriented in differentcrystallographic orientations.We then move onto the fabrication and study of a single hole transistor in a GaAs/AlGaAsheterostructure. The Coulomb blockade oscillations resulting from single hole chargestunnelling on/off the quantum dot are observed and we also measure the charging energy ofthe quantum dot with source-drain bias spectroscopy. The quantum dot is found to be morestable and has less electrical noise compared to a single electron transistor fabricated onsilicon, and compares favourably with an electron quantum dot fabricated on a GaAs/AlGaAsheterostructure with modulation dopants.We also fabricated the first ambipolar devices on a GaAs/AlGaAs heterostructure with theMISFET design and characterised these devices at low temperatures. Firstly the chargetransport of electrons and holes are compared directly in a 2D ambipolar device bymeasuring the density dependence of the carrier mobility. It is observed that the electronmobility can be modelled with charge scattering theories taking into account backgroundimpurity scattering, interface roughness scattering and screening. However, when the samefitting parameters are used to model the hole mobility by switching the effective mass ofelectrons to holes, the theory cannot fit the experimental hole mobility. Several possibilitiesfor the deviation of the calculations are discussed but further experimental and theoreticalworks need to be conducted in order to determine the exact cause for this deviation.Finally we characterised ambipolar 1D wires where both electrons and holes can bemeasured. Ballistic transport of both types of charge carriers is observed and we comparethe 1D subband spacings of electrons to holes.

▼ The physical properties and the excitations spectrum in oxides and semiconductors materials are presented in this work, whose the first part presents a study on the confinement of optical phonons in artificial systems based on III-V nitrides, grown in periodic and quasiperiodic forms. The second part of this work describes the Ab initio calculations which were carried out to obtain the optoeletronic properties of Calcium Oxide (CaO) and Calcium Carbonate (CaCO3) crystals. For periodic and quasi-periodic superlattices, we present some dynamical properties related to confined optical phonons (bulk and surface), obtained through simple theories, such as the dielectric continuous model, and using techniques such as the transfer-matrix method. The localization character of confined optical phonon modes, the magnitude of the bands in the spectrum and the power laws of these structures are presented as functions of the generation number of sequence. The ab initio calculations have been carried out using the CASTEP software (Cambridge Total Sequential Energy Package), and they were based on ultrasoft-like pseudopotentials and Density Functional Theory (DFT). Two di®erent geometry optimizations have been e®ectuated for CaO crystals and CaCO3 polymorphs, according to LDA (local density approximation) and GGA (generalized gradient approximation) approaches, determining several properties, e. g. lattice parameters, bond length, electrons density, energy band structures, electrons density of states, e®ective masses and optical properties, such as dielectric constant, absorption, re°ectivity, conductivity and refractive index. Those results were employed to investigate the confinement of excitons in spherical [email protected] and [email protected] quantum dots and in calcium carbonate nanoparticles, and were also employed in investigations of the photoluminescence spectra of CaCO3 crystal Advisors/Committee Members: Albuquerque, Eudenilson Lins de (advisor), CPF:05011124487 (advisor), http://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4783172H5 (advisor), Freire, Valder Nogueira (advisor), CPF:12105473334 (advisor), http://lattes.cnpq.br/8647922327100953 (advisor).

The physical properties and the excitations spectrum in oxides and semiconductors materials are presented in this work, whose the first part presents a study on the confinement of optical phonons in artificial systems based on III-V nitrides, grown in periodic and quasiperiodic forms. The second part of this work describes the Ab initio calculations which were carried out to obtain the optoeletronic properties of Calcium Oxide (CaO) and Calcium Carbonate (CaCO3) crystals. For periodic and quasi-periodic superlattices, we present some dynamical properties related to confined optical phonons (bulk and surface), obtained through simple theories, such as the dielectric continuous model, and using techniques such as the transfer-matrix method. The localization character of confined optical phonon modes, the magnitude of the bands in the spectrum and the power laws of these structures are presented as functions of the generation number of sequence. The ab initio calculations have been carried out using the CASTEP software (Cambridge Total Sequential Energy Package), and they were based on ultrasoft-like pseudopotentials and Density Functional Theory (DFT). Two dierent geometry optimizations have been eectuated for CaO crystals and CaCO3 polymorphs, according to LDA (local density approximation) and GGA (generalized gradient approximation) approaches, determining several properties, e. g. lattice parameters, bond length, electrons density, energy band structures, electrons density of states, eective masses and optical properties, such as dielectric constant, absorption, reectivity, conductivity and refractive index. Those results were employed to investigate the confinement of excitons in spherical [email protected] and [email protected] quantum dots and in calcium carbonate nanoparticles, and were also employed in investigations of the photoluminescence spectra of CaCO3 crystal

▼ Strain-coupled multiferroic heterostructures provide a path to energy-efficient, voltage-controlled magnetic nanoscale devices, a region where current-based methods of magnetic control suffer from Ohmic dissipation. Magnetoelectric coupling behavior in such composite heterostructures has thus been of substantial interest for scientific research and applications. As the dimension of the devices scale down, novel physical phenomenon emerges and thus also requires further understanding of both the magnetization and strain behavior at micro- and nanoscale. When it comes to the magnetization behavior, there has been a growing interest in highly magnetoelastic materials, such as Terfenol-D, prompting a more accurate understanding of their magnetization behavior. To address this need, we simulate the strain-induced magnetization change with two modeling methods: the commonly used unidirectional model and the recently developed bidirectional model. Unidirectional models account for magnetoelastic effects only, while bidirectional models account for both magnetoelastic and magnetostrictive effects. We found unidirectional models are on par with bidirectional models when describing the magnetic behavior in weakly magnetoelastic materials (e.g., Nickel), but the two models deviate when highly magnetoelastic materials (e.g., Terfenol-D) are introduced. These results suggest that magnetostrictive feedback is critical for modeling highly magnetoelastic materials, as opposed to weaker magnetoelastic materials, where we observe only minor differences between the two methods’ outputs. To our best knowledge, this work represents the first comparison of unidirectional and bidirectional modeling in composite multiferroic systems, demonstrating that back-coupling of magnetization to strain can inhibit formation and rotation of magnetic states, highlighting the need to revisit the assumption that unidirectional modeling always captures the necessary physics in strain-mediated multiferroics. In terms of the strain behavior, there hasn’t been a system-level work that quantifies the strain distribution as a function of the electric field at these so-called mesocales level (100 nm- 10 um), in the range of the constitutive grain size, etc. To obtain mechanical properties at such length scale, including strain information, we used synchrotron polychromatic scanning x-ray diffraction (micro-diffraction) on beamline 12.3.2 at the Advanced Light Source of the Lawrence Berkeley National Lab. With given ferromagnetic and ferroelectric components, it is the magnetoelectric coupling between the two that governs the interaction. In this work, we also demonstrate a method to enhance the coupling behavior between two existing components by interposing a polymer layer.

Aluminum nitride (AlN), Gallium nitride (GaN) and its ternary alloy Aluminum Gallium Nitride (AlGaN) are the potential materials for ultraviolet emitters and detectors due to their direct wide band gap. The ultraviolet light emission from AlxGa1-xN can be tunable from 360 (GaN) to 200 (AlN) nm by varying the aluminum composition (x) from 0 to 100 %. The lack of native substrates forces the heteroepitaxial growth of AlN, GaN and AlGaN on sapphire (Al2O3) and silicon carbide (SiC) substrates. For cost reasons, c-plane sapphire is often used despite the large lattice mismatch and large difference in thermal expansion. AlN has been used as the buffer layer for AlGaN layer based deep ultraviolet (DUV) light emitting devices to accommodate the mismatches and reduce the dislocation density. AlN possesses excellent UV light transparency and excellent lattice match with high Al content AlGaN layers. In addition, AlN has high thermal conductivity (3.2 W cm-1 K-1) and high breakdown voltage (12 MV cm-1) essential for high-power and high temperature electronic devices. However, growth of AlN has many challenges due to the heteroepitaxy, high sticking coefficient of Aluminum (Al), parasitic reactions between Al and ammonia (NH3), etc. Despite these challenges, growth of AlN epilayers have been studied in detail with the AlN nucleation layers to improve the crystalline quality. On the other part, investigations on the radiation tolerance and defect resistance of AlGaN/GaN heterostructures upon swift heavy irradiation at room and low temperature have been carried out. Iv Growth of high temperature (HT) - AlN layers with nucleation layers have been performed using high temperature hydride vapor phase epitaxy (HT-HVPE) at 1200 and 1400 °C. The influence of growth temperature and HT-treatment on AlN nucleation layer (NL) morphology and thickness have been studied. It has been concluded that the rearrangement of the AlN-NL surface during HT-treatment at 1200 °C.
