▼ A central question in the field of heterogeneous catalysis is how surface structure and subsurface species influence catalytic behavior. One key to answering that question is determining which surface structures and subsurface species are present under catalytically relevant conditions. This dissertation presents results of Auger electron spectroscopy, low energy electron diffraction, temperature programmed desorption, and scanning tunneling microscopy experiments on oxidized Rh(111) and Ag(111) crystals. Exposing Rh(111) to O2 produced a predominately (2 × 1) adlayer, but even after extended dosing, (2 × 2) domains were also present. Exposing Rh(111) to atomic oxygen yielded O coverages greater than 0.5 ML and (1 × 1) domains were observed to form along terrace step edges. However, (2 × 1) and (2 × 2) domains were still present. Atomic oxygen was used to oxidize Ag(111) in order to study the effect of sample temperature as well as oxygen flux and energy. When atomic oxygen was generated using a lower temperature thermal cracker, a variety of previously reported surface structures were observed. When O was generated using a higher filament temperature, the surface became highly corrugated, layers of Ag2O appeared to form, and little subsurface oxygen was observed. To investigate the role of sample temperature, the Ag(111) sample was held at various temperatures while being exposed to atomic oxygen. For short doses, sample temperature had minimal effect on surface reconstruction. For longer doses, changes in sample temperature in the range of 490 K to 525 K had a substantial impact on surface reconstruction and subsurface oxygen absorption. Higher temperature dosing yielded the same surface structures which were observed after short doses. Lower temperature dosing with atomic oxygen resulted in subsurface oxygen formation and new structures which covered the surface. The results indicate the rich complexity of oxygen/transition metal interactions and illustrate how reactive species can be used to produce high coverage surface structures under UHV conditions.

▼ Spin-orbit coupling (SOC) is the interaction of an electron's intrinsic angular momentum (spin) with its orbital momentum. The strength of this interaction is proportional to Z⁴ where Z is the atomic number, so generally it is stronger in atoms with higher atomic number, such as bismuth (Z=83) and iridium (Z=77). In materials composed of such heavy elements, the prominent SOC can be sufficient to modify the band structure of the system and lead to distinct phase of matter. In recent years, SOC has been demonstrated to play a critical role in determining the unusual properties of a variety of compounds. SOC associated materials with exotic electronic states have also provided a fertile platform for studying emergent phenomena as well as new physics. As a consequence, the research on these interesting materials with any insight into understanding the microscopic origin of their unique properties and complex phases is of great importance. In this context, we implement scanning tunneling microscopy (STM) and spectroscopy (STS) to explore the surface states (SS) of the two major categories of SOC involved materials, Bi-based topological insulators (TI) and Ir-based transition metal oxides (TMO). As a powerful tool in surface science which has achieved great success in wide variety of material fields, STM/STS is ideal to study the local density of states of the subject material with nanometer length scales and is able to offer detailed information about the surface electronic structure. In the first part of this thesis, we report on the electronic band structures of three-dimensional TIs Bi₂Te₃ and Bi₂Se₃. Topological insulators are distinct quantum states of matter that have been intensely studied nowadays. Although they behave like ordinary insulators in showing fully gapped bulk bands, they host a topologically protected surface state consisting of two-dimensional massless Dirac fermions which exhibits metallic behavior. Indeed, this unique gapless surface state is a manifestation of the non-trivial topology of the bulk bands, which is recognized to own its existence to the strong SOC. In chapter 3, we utilize quasiparticle interference (QPI) approach to track the Dirac surface states on Bi₂Te₃ up to ~800 meV above the Dirac point. We discover a novel interference pattern at high energies, which probably originates from the impurity-induced spin-orbit scattering in this system that has not been experimentally detected to date. In chapter 4, we discuss the topological SS evolution in (Bi_1-xIn_x)₂Se₃ series, by applying Landau quantization approach to extract the band dispersions on the surface for samples with different indium content. We propose that a topological phase transition may occur in this system when x reaches around 5%, with the experimental signature indicating a possible formation of gapped Dirac cone for the surface state at this doping. In the second part of this thesis, we focus on… Advisors/Committee Members: Vidya Madhavan (Thesis advisor).

▼ A Pan-style scanning tunneling microscope (STM), with a vertical coarse approach mechanism, was designed, built and tested. The microscope will be operated in ultra-high vacuum and also at cryogenic temperatures (8 K) inside a continuous flow cryostat. Fundamental differences in operating principle exist between the new microscope and the beetle-type inertial sliders [1] that have been the mainstay of the group for the last eight years. While Pan-style microscopes do already exist [2], they remain challenging to build, and an active area of research [3]. This system represents a bold departure from well-trodden paths, and will greatly expand the range of experiments that our group can perform. The operating principles of inertial piezoelectric motors are detailed. Design guidelines for a piezoelectric motor are given, and used in the design of the vertical coarse approach motor. A simple, inexpensive implementation for creating waveforms with an extremely fast fall time is discussed. Motor performance is tested, and a minimum step size of 20nm is found for frequencies ranging from 0 Hz to 3 kHz. The motor operates with high dynamic range: individual 20nm steps can be taken, as well as being able to move at a velocity of 0.4mm s−1. Little is known about the vibrational properties of Pan-style microscopes. Vibrational testing of the microscope revealed the expected scanner bending mode at 1.6 kHz (above the scanner bending mode of our beetles at 1.2 kHz), and a complicated response signal above this frequency. Custom extension springs for an eddy-current damping system are built and tested. A low resonant frequency of 1.8 Hz is found, which is ideal for the application. Initial testing of the STM in ambient conditions is performed on two different surfaces. A moir´e supermesh [4] with periodicity 3nm is observed on a highly-oriented pyrolytic graphite (HOPG) surface, and agrees well with previously published results. Using a flame-annealed Gold on mica surface, a low drift rate of 0.6nm s−1 is observed over a period of 13 minutes. Single-height atomic steps are observed on both surfaces. Additionally, the microscope is shown to be capable of zooming into different features on a surface, and scanning at different length scales.

▼ This research work is aimed at understanding the electronic properties of Bi(110) nanostructures. This study chiefly uses Scanning Tunneling Microscopy (STM), Scanning Tunneling Spectroscopy (STS) and Non Contact Atomic Force Microscope (NCAFM) to investigate the geometric and electronic structure of Bi(110) islands on highly oriented pyrolytic graphite (HOPG) substrate. STM measurements are the primary focus of the thesis which involves imaging the bismuth islands and study of its atomic structure. STM images of the Bi(110) islands reveal a ‘wedding cake’ profile of the bismuth islands that show paired layers on top of a base. I(V) (Current vs voltage) data was acquired via STS techniques and its first derivative was compared to DFT calculations. The comparison implied the presence of a dead wetting layer which was present only underneath the bismuth islands. We observed bilayer damped oscillations in the surface energy that were responsible for the stability of paired layers in Bi(110) islands. Interesting Moiré pattern arising out of misorientation between the substrate and the overlayer are also observed in STM images on some bismuth islands. Bright features pertaining to enhanced LDOS (local density of states) were observed on the perimeter of the bismuth islands and stripes in the STM images and STS dI/dV maps which appear at energies around the Fermi level. The bright features which we termed as ‘bright beaches (BB)’ are also observed on grain boundaries and defects that suggest that they are related to termination of the chain of bismuth atoms. The Bi(110) islands and stripes were observed to form preferred widths with a well defined periodicity. This peculiar phenomenon was attributed to a lateral quantum size effect (QSE) that results from a Fermi wave vector with appropriate shifts in Fermi energy. The widths of the islands prefer to adjust themselves at the nodes of this in-plane Fermi wavelength. NaCl deposited on a HOPG substrate forms cross shaped islands which were used as spacers to limit the interaction between the bismuth films and the underlying HOPG substrate. The NaCl islands are transparent to the flow of tunneling current and allow STS measurements. The LDOS of Bi/HOPG was very similar to the LDOS of Bi deposited on NaCl/HOPG which suggests that the wetting layer underneath the bismuth islands plays an important role in decoupling the film from the underlying substrate.

▼ This dissertation presents results of scanning tunneling microscopy/spectroscopy experiments performed on graphene, a two-dimensional membrane of carbon atoms arranged in a honeycomb lattice, where charge carriers behave like massless fermions described by the Dirac equation. Our findings demonstrate that interface engineering is a viable route to control and further enhance the electronic properties of graphene. In the first experiment, by transferring chemical vapor deposited (CVD) graphene onto substrates of opposite polarization - H-terminated Si-face and C-faces of hexagonal silicon carbide (SiC), we show that the type of charge carrier in graphene can be controlled by substrate polarization. Furthermore, we find that the charge carrier in epitaxial graphene/Si-face SiC(0001) convert from n- to p-type upon H-intercalation at the interface. Finally, we observe the formation of ripples in the graphene H-terminated SiC heterojunctions, which causes atomic scale fluctuations in the Dirac point. Density functional theory calculations suggest the formation of a Schottky dipole just ~ 1 nm at the graphene/SiC interface, thus the Dirac point depends strongly on the spacing between graphene and SiC. As a result, ripples, i.e., atomic scale topographic fluctuations of graphene with respect to the substrate, lead to the variations in the Dirac point. In the second experiment, we discover two types of intrinsic atomic-scale inhomogeneities that can cause fluctuations in the Schottky barrier height at graphene/semiconductor junctions: graphene ripples and/or trapped charge impurities and surface states of the semiconductor. These findings provide insight into the fundamental physics of nanoscale devices based on graphene - semiconductor junctions. In the third experiment, we experimentally demonstrate proximity-induced spin-orbit coupling in graphene-topological insulator van der Waals (vdW) heterostructures fabricated by transferring CVD graphene onto Bi2Se3 grown by molecular beam epitaxy. We observe a spin-orbit splitting of up to 80 meV in the graphene Dirac states, an enhancement of several orders of magnitude compared to the intrinsic value. Moreover, the spin-orbit splitting exhibits spatial variations of ±20 meV, as a result of the lack of epitaxial relation between the graphene and Bi2Se3 layers. Density functional theory calculations further reveal that this giant spin-orbit splitting of the graphene bands is a consequence of the orthogonalization requirement on the overlapping wave functions, rather than arising from simple direct bonding at the interface. This revelation of the indirect bonding mechanism of the proximity effect is an enabling step towards more effective engineering of desired properties in vdW heterostructures.

▼ Materials science is the cornerstone for technological development of the modern world that has been largely shaped by the advances in fabrication of semiconductor materials and devices. However, the Moore’s Law is expected to stop by 2025 due to reaching the limits of traditional transistor scaling. However, the classical approach has shown to be unable to keep up with the needs of materials manufacturing, requiring more than 20 years to move a material from discovery to market. To adapt materials fabrication to the needs of the 21st century, it is necessary to develop methods for much faster processing of experimental data and connecting the results to theory, with feedback flow in both directions. However, state-of-the-art analysis remains selective and manual, prone to human error and unable to handle large quantities of data generated by modern equipment. Recent advances in scanning transmission electron and scanning tunneling microscopies have allowed imaging and manipulation of materials on the atomic level, and these capabilities require development of automated, robust, reproducible methods.Artificial intelligence and machine learning have dealt with similar issues in applications to image and speech recognition, autonomous vehicles, and other projects that are beginning to change the world around us. However, materials science faces significant challenges preventing direct application of the such models without taking physical constraints and domain expertise into account.Atomic resolution imaging can generate data that can lead to better understanding of materials and their properties through using artificial intelligence methods. Machine learning, in particular combinations of deep learning and probabilistic modeling, can learn to recognize physical features in imaging, making this process automated and speeding up characterization. By incorporating the knowledge from theory and simulations with such frameworks, it is possible to create the foundation for the automated atomic scale manufacturing.

▼ The aim of this thesis is to characterize the properties of a Josephson junction in a Scanning Tunneling Microscope (STM) at millikelvin temperatures and to implement Josephson STM (JSTM) as a versatile probe at the atomic scale. To this end we investigate the I(V) tunneling characteristics of the Josephson junction in our STM at a base temperature of 15 mK by means of current-biased and voltage-biased experiments. We find that in the tunneling regime, the Josephson junction is operated in the dynamical Coulomb blockade (DCB) regime in which the sequential tunneling of Cooper pairs dominates the tunneling current. Employing P(E)-theory allows us to model experimental I(V) characteristics from voltage-biased experiments and determine experimental values of the Josephson critical current in agreement to theory. Moreover, we observe a breakdown of P(E)-theory for experiments at large values of the tunneling conductance on the order of the quantum of conductance, which could indicate that the coherent tunneling of Cooper pairs strongly contributes to the tunneling current in this limit. We also observe that the Josephson junction in an STM at temperatures well below 100 mK is highly sensitive to its electromagnetic environment that results from its tiny junction capacitance of a few femtofarads. The combination of the experimental results with numerical simulations reveals that the immediate environment of the Josephson junction in an STM is frequency-dependent and, additionally, that a typical STM geometry shares the electromagnetic properties of a monopole antenna with the STM tip acting as the antenna. Comparing the I(V) curves of voltage-biased and current-biased experiments, we observe that the time evolution of the phase is strongly effected by dissipation due to quasiparticle excitations. From investigations on the retrapping current we show first that the temporal evolution of the junction phase in our STM satisfies a classical equation of motion. Second, we can determine two different channels for energy dissipation of the junction phase. For tunneling resistance values RN< 150 kOhm the junction dissipates via Andreev reflections whereas for larger values of RN <150 kOhm the energy dissipation is dominated by lifetime effects of Cooper pairs. Moreover, from comparing both experiments we also observe that the quantum-mechanical nature of the junction phase manifests itself in quantum-mechanical phenomena, such as phase tunneling, which strongly alter our experimental I(V) characteristics for GN<=G0. To conclude, within this thesis we characterized the properties of a Josephson junction in an STM that is operated at millikelvin temperatures. Hence, this work represents necessary and fundamental steps that allows us to employ the Josephson effect as a versatile probe on the atomic scale. Advisors/Committee Members: Kern, Klaus.

Inventado no início dos anos 1980, o STM evoluiu para uma importante ferramenta na investigação das propriedades de superfícies e interfaces, com aplicações em várias áreas da ciência além da Física, como Ciências de Materiais e Química. O presente trabalho trata da microscopia de tunelamento, que se baseia no fenômeno do tunelamento quântico dos elétrons. No STM, a distância entre ponta e a amostra é reduzida até que as funções de onda dos elétrons na ponta e na superfície da amostra se sobreponham. Nessa situação, observa-se o fenômeno do tunelamento quântico de elétrons através da barreira formada entre os dois eletrodos (ponta e amostra). Como o valor da corrente de tunelamento é fortemente dependente da distância ponta-amostra, um microscópio STM pode ser utilizado para mapear a morfologia da superfície da amostra com alta resolução espacial. Além disso, outra importante capacidade do STM é a possibilidade de atuar no modo espectroscópico (STS). Por vezes, o estudo detalhado das propriedades de um sistema requer o uso de métodos não convencionais de microscopia STM. Um exemplo é o estudo do magnetismo de nanoestruturas por microscopia de tunelamento com resolução em spin (SP-STM). A implementação destes métodos não convencionais normalmente exigem recursos experimentais específicos, nem sempre disponíveis em equipamentos comercias. A versatilidade no controle das características funcionais do equipamento foi a principal razão que nos motivou a construir o microscópio STM. No primeiro capitulo faremos uma introdução geral ao tema da dissertação. Uma breve introdução ao método de STM será dada no capítulo 2, incluindo aspectos fundamentais do tunelamento quântico, bem como sua aplicação técngeralica. O capítulo 3 descreve o estudo das propriedades eletrônicas e magnéticas do grafeno preparado sobre a superfície vicinal Ni(977). O magnetismo observado na camada de grafeno induzido por um substrato ferromagnético é de grande interessante para o desenvolvimento de dispositivos spintrônicos. Relatamos a investigação das propriedades de uma monocamada de grafeno preparada sobre de Ni(977) por CVD, utilizando a microscopia de varredura por tunelamento (STM), dicroísmo circular magnético de raios-x (XMCD) e espectroscopia de fotoelétrons (XPS). No capítulo 4, apresentamos o detalhamento do projeto de construção de um STM para operar em ambiente de ultra alto vácuo (UHV). Características do STM como isolamento de vibração, desenho mecânico, sistema de varredura e processo de preparação de pontas são discutidos. Por fim, analisamos os resultados dos testes de operação no microscópio STM, dificuldades observadas ao longo do projeto e possíveis melhorias.

Invented in the early 1980s, STM has evolved into a standard tool to investigate the properties of surfaces and interfaces, with applications in various research fields, such as physics, material sciences and chemistry. The present work deals with scanning tunnelling microscopy, which refers to the quantum phenomenon of electron tunneling through a potential barrier. The…
