▼ A large variety of two-dimensional (2D) materials exhibit unique physical and chemical properties. Detailed knowledge of the structure and dynamical properties of these intriguing modern materials is essential for developing a fundamental understanding of their properties. In this thesis, investigations of the structure, morphology, and dynamics of 2D materials on metal substrates have been carried using low energy electron microscopy (LEEM) and diffraction (LEED). The interplay of complementary anisotropic strain relief by nano-wrinkles and substrate-induced corrugation in graphene on a vicinal copper surface is found to induce one dimensional nano-wrinkle morphology perpendicular to facets/steps on the underlying substrate. The residual compressive strain is determined using high spatially-resolved μLEED measurements to be 0.7% and 0.3% perpendicular to nano-wrinkles and facets, respectively. The substrate facets that induce corrugation in graphene are identified using LEED facet spot analysis to be (110), (531), (351) and (665). This behavior contrasts with random wrinkle network that was observed in the absence of substrate-induced corrugation on a singular copper surface. We also observed the formation of a new oxygen-deficient 2D copper oxide structure at the Cu(111) surface that exhibits intriguing domain pattern formation and dynamical behavior. This structure may be attributed to a honeycomb-like Cu₂O(111) surface oxide layer with a periodic array of Stone–Wales defects. Depletion of oxygen by thermal desorption is accommodated by the formation of oxygen-free regions that coexist with the oxide structure in a sequence of island, stripe and inverse island patterns with decreasing oxygen content. Several sequential evolution mechanisms of the characteristic length scale are identified by rescaling analysis of the structure function that is measured from observations of phase separation during cooling. Further development of LEEM image formation theory was also performed to support extension of the work described in this thesis in the future. The extended Fourier Optics (FO) approach for modeling image formation in aberration-corrected LEEM is presented. This work broadens our capabilities to understand the origins of LEEM image contrast and to perform quantitative evaluation of contrast.

Vacuum created model systems give the possibility for detailed study of the substrate–adsorbate interaction. In this work two systems have been created by vacuum deposition and these have been characterized with different electron spectroscopies. A chromium oxide model catalyst has been studied with X-ray photoelectron spectroscopy (XPS) and a magnetically interesting epitaxial Co/Cu system has been characterized with low energy electron diffraction (LEED). Alumina supported chromium oxides are widely used as dehydrogenation catalysts. The nature of the active sites and the reaction paths are still somewhat unclear. We have used the model catalyst approach in order to understand the properties of supported chromium oxide catalysts. The growth of chromium on a thin alumina film has been studied. The oxidation and reduction of this model catalyst and alumina supported chromium oxide catalysts have been compared. The model catalyst can be oxidized under vacuum to the active oxidation state Cr3+, but not further. In calcination and reduction the model catalyst was found to exhibit similar behavior as supported catalyst. This similarity suggests that the model catalyst can be used to study e.g. dehydrogenation reactions carried out on supported chromium oxides despite of the structural differences. The chemical state information obtained from XPS measurements by peak fitting is subject to many systematic and random errors. We have studied the effect of the background subtraction method on the derived chemical state proportions of chromium and iron oxides with two oxidation states. The effect of the background choice was found to be comparable to typical systematic errors related to uncertain peak fitting parameters. Epitaxial layers of Co and Cu show interesting magnetic properties, such as giant magnetoresistance. Undesired interface mixing has been observed when growing these layers. In this work Co was deposited onto a Cu(001) single crystal to model the interface structure. Co was found to form random surface alloys exhibiting substitutional copper sites. When the Co coverage increases to several monolayers, a transition to layer growth is observed. These findings can be used to model the magnetic properties of Co/Cu layers.

▼ The interest in two-dimensional materials and materials physics has grown dramatically over the past decade. The family of two-dimensional materials, which includes graphene, transition metal dichalcogenides, phosphorene, hexagonal boron nitride, etc., can be fabricated into atomically thin films since the intralayer bonding arises from their strong covalent character, while the interlayer interaction is mediated by weak van der Waals forces. Among them, molybdenum disulfide (MoS₂) has attracted much interest for its potential applications in opto-electronic and valleytronics devices. Previously, much of the experimental studies have concentrated on optical and transport measurements while neglecting direct experimental determination of the electronic structure of MoS₂, which is crucial to the full understanding of its distinctive properties. In particular, like other atomically thin materials, the interactions with substrate impact the surface structure and morphology of MoS₂, and as a result, its structural and physical properties can be affected. In this dissertation, the electronic structure and surface structure of MoS₂ are directly investigated using angle-resolved photoemission spectroscopy and cathode lens microscopy. Local-probe angle-resolved photoemission spectroscopy measurements of monolayer, bilayer, trilayer, and bulk MoS₂ directly demonstrate the indirect-to-direct bandgap transition due to quantum confinement as the MoS₂ thickness is decreased from multilayer to monolayer. The evolution of the interlayer coupling in this transition is also investigated using density functional theory calculations. Also, the thickness-dependent surface roughness is characterized using selected-area low energy electron diffraction (LEED) and the surface structural relaxation is investigated using LEED I-V measurements combined with dynamical LEED calculations. Finally, bandgap engineering is demonstrated via tuning of the interlayer interactions in van der Waals interfaces by twisting the relative orientation in bilayer-MoS₂ and graphene-MoS₂-heterostructure systems.

▼ In the low optical frequency limit, photoionization processes in atoms and molecules irradiated with intense ultrafast laser fields can be described within the quasi-static tunneling framework. Higher order processes of the photoelectron dynamics were observed and attributed to the recollision of the tunneled electrons. Development of the quantitative rescattering theory laid a foundation for retrieving field-free differential cross section (DCS) from the distribution of rescattered photoelectrons. Due to technological reasons, the majority of strong field physics experiments were carried out at near-infrared wavelengths 0.8 μ m or 1 μ m. Retrieved DCS' at these wavelengths were not very accurate since these laser frequencies are high and the systems do not strictly satisfy the quasi-static tunneling condition. Here we present the accurate retrieval of noble gas atom DCS' from photoelectron distributions under mid-infrared laser radiation. These lower frequency fields not only result in better quasi-static tunneling initial conditions, but also higher photoelectron recollision energies, core penetrating collisions and improved spatial resolutions, suitable for molecular imaging. Bond lengths of nitrogen and oxygen molecules were extracted from the rescattered photoelectron distributions. This method is called laser-induced electron diffraction (LIED). Alternatively, utilizing the broadband nature of recolliding photoelectrons, bond length of the nitrogen molecule was extracted from a Fourier transform of the backscattered photoelectron spectrum along the laser polarization direction. This is the fixed-angle broadband laser-driven electron scattering (FABLES). Both LIED and FABLES rely on well defined recollision geometries, so molecular alignment is needed to generalize both imaging methods for more complex molecules.Theoretical and experimental evidence shows that the Coulomb potential of the parent ion can be safely ignored during the high-energy recollisions in LIED and FABLES. However, this is not true for the case of low-energy, small-angle recollisions. Evidence of this is the photoelectron low-energy structure (LES). Soon after the discovery of the LES, theoretical studies attributed its origin to an interplay between the Coulomb field of the parent ion and the electric field of the laser. The type of electron trajectories responsible for the LES are those leading to soft-recollisions, taking place about one and half laser cycles after tunneling ionization. So far, most LES experiments were conducted with multi-cycle pulses where the envelope of the laser electric field is practically constant. Here we present LES measurements with few-cycle laser pulses of various pulse durations. Since in this case the envelope of the laser electric field changes drastically from cycle to cycle and hence during the soft-recollision motion of the LES photoelectrons, changes in the LES peak position as a function of laser pulse duration were expected and observed. Classical trajectory Monte Carlo simulations… Advisors/Committee Members: DiMauro, Louis (Advisor).

▼ This dissertation reports on a novel theoretical and computational framework for calculating low-energy electron reflectivities from crystalline surfaces and its application to two layered systems of two-dimensional materials, graphene and molybdenum disulfide. The framework provides a simple and efficient approach through the matching of a small set of Fourier components of Bloch wave solutions to the Schrodinger Equation in a slab-in-supercell geometry to incoming and outgoing plane waves on both sides of the supercell. The implementation of this method is described in detail for the calculation of reflectivities in the lowest energy range, for which only specular reflection is allowed. This implementation includes the calculation of reflectivities from beams with normal or off-normal incidence. Two different algorithms are described in the case of off-normal incidence which differ in their dependence on the existence of a symmetry with a mirror plane parallel to the crystal surface. Applications to model potentials in one, two, and three dimensions display consistent results when using different supercell sizes and convergent results with the density of Fourier grids. The design of the Bloch wave matching also allows for the accurate modeling of crystalline slabs through the use of realistic potentials determined via density functional theory. The application of the method to low-energy electron scattering from free-standing systems of a few layers of graphene, including the use of these realistic potentials, demonstrates this ability of the method to accurately model real systems. It reproduces the layer-dependent oscillations found in experimental, normal incidence reflectivity curves for a few layers of graphene grown on silicon carbide. The normal incidence reflectivity curves calculated for slabs consisting of few-layer graphene on 10 layers of nickel show some qualitative agreement with experiment. General incidence reflectivity spectra for free-standing few-layer graphene predict free-electron-like dispersion for the location of the lowest energy oscillations as a function of the in-plane Bloch wave vector, as well as other interesting features. The application of the method to scattering from free-standing systems of molybdenum disulfide predicts that low-energy electron reflectivities can provide a means for layer counting, especially in 2H- and 3R-molybdenum disulfide, and structural differentiation, especially between 1T- and 2H-molybdenum disulfide, in few-layer systems. An investigation of the issues and limitations of the method suggests that some modifications and improvements are likely necessary before widespread application is possible.

▼ Atomic steps are common defects at surfaces that can play an important role in many physical phenomena. Step morphology will be affected, or even dictated, by the kinetic processes that mediate growth and its inverse, sublimation. At the same time, competing coarsening processes will occur that depend crucially upon the step line tension through the Gibbs-Thomson relation. A proper description of step morphological phenomena therefore requires accurate knowledge of step line tension, as well as step kinetic parameters. The complex interplay between step kinetic and coarsening effects was investigated on the Si(111) (1x1) surface by examining step motion during island decay using low energy electron microscopy. These investigations provide quantitative information on the step line tension, kinetic length and step permeability. It is shown that the line tension decreases linearly with increasing temperature between 1145 K and 1233 K with a temperature coefficient of −0.14 meV/Å K. The kinetic length is determined to be 75a at 1163K, where a is the lattice constant. This locates step motion firmly in the diffusion-limited regime. Steps are also determined to be impermeable in the context of diffusion limited step kinetics. We also find that the role of desorption in island decay increases dramatically in the temperature range (1145−1380 K) that island decay is studied. Consequently, we generalize the current model of island decay to take account of desorption. Evaluation of the island decay time with this model referenced to the temperature-dependent line tension accurately determines activation energies that are central to mass transport and sublimation. Similar investigations of vacancy island decay were also carried out. Surprisingly, island decay and vacancy island decay behavior cannot be explained consistently using any form of model that treats mass transport exclusively in terms of the diffusion of adatoms that are generated at steps. An adatom-vacancy decay model is proposed to address this problem. The foregoing experimental investigations are possible because of the capability of LEEM to image the motion of atomic height surface steps in real-time. In order to better understand this unique capability, a Fourier optics calculation of image formation in LEEM is carried out. The adaptation of the existing Fourier optics theory for transmission electron microscopy to the treatment of LEEM is explained. The model calculation incorporates imaging errors that are caused by the objective lens, contrast aperture, imperfect source characteristics, and voltage and current instabilities. It is used to evaluate the appearance of image features that arise from pure phase objects such as surface steps as well as amplitude objects. Resolution and the predicted experimental observation is also discussed. This formalism can also be used after appropriate modification to treat image formation in other emission microscopies.

▼ Chemical doping is a well-established method for controlling the electronic properties of bulk semiconductors and, e.g, complex oxide materials. In this process, dopant atoms are located at substitutional lattice locations, from where they introduce free charge carriers to the host material. These carriers greatly improve the electrical conductivity of the host material and can even induce an insulator-metal transition at high doping levels. Dopants, however, also introduce scattering centers that are detrimental to conductivity, especially in low-dimensional systems such as nanowires and ultrathin films. These problems can be overcome by using a modulation doping approach in which the dopant atoms are spatially separated from the conducting layers via heterostructure engineering. In a recent study, Mulugeta and coworkers were able to induce a symmetry-breaking metal insulator transition in an atomic bilayer of Sn on Si(111), by substituting Si atoms in the substrate with boron. However, the structure of the Sn layer is still under dispute and it is not clear where precisely the boron atoms are located and whether the Sn bilayer structure is significantly altered by the boron. The resolve this issue, we performed structure studies on both doped and undoped Sn bilayers, using low-energy electron diffraction (LEED). The intensities of the diffracted beams were recorded as a function of beam voltage and the resulting I(V) curves served as input for the structural refinement with a dynamical diffraction structure code. Various structure models were tested by our collaborators at Penn State University. The structure model proposed by Ichikawa (REF) produces the best fit to the I(V) spectra, although further refinement remains necessary. Comparison of the I(V) spectra of the doped and undoped Sn layers strongly suggests that the boron atoms are indeed located below the Sn layer. Furthermore, it can be stated with great certainty that the doped and undoped Sn layers have identical structures. Hence, the metal-insulator transition observed by Mulugeta et al. can indeed be attributed to carrier doping. Advisors/Committee Members: Hanno Weitering, Norman Mannella, Marianne Breinig.

▼ The direct epitaxial growth of multilayer BN by atomic layer deposition is of critical significance forfo two-dimensional device applications. X-ray photoelectron spectroscopy (XPS) and low energy electron diffraction (LEED) demonstrate layer-by-layer BN epitaxy on two different substrates. One substrate was a monolayer of RuO2(110) formed on a Ru(0001) substrate, the other was an atomically clean Ni(111) single crystal. Growth was accomplished atomic layer deposition (ALD) cycles of BCl3/NH3 at 600 K substrate temperature and subsequent annealing in ultrahigh vacuum (UHV). This yielded stoichiometric BN layers, and an average BN film thickness linearly proportional to the number of BCl3/NH3 cycles. The BN(0001)/RuO2(110) interface had negligible charge transfer or band bending as indicated by XPS and LEED data indicate a 30° rotation between the coincident BN and oxide lattices. The atomic layer epitaxy of BN on an oxide surface suggests new routes to the direct growth and integration of graphene and BN with industrially important substrates, including Si(100). XPS and LEED indicated epitaxial deposition of h-BN(0001) on the Ni(111) single crystal by ALD, and subsequent epitaxially aligned graphene was deposited by chemical vapor deposition (CVD) of ethylene at 1000 K. Direct multilayer, in situ growth of h-BN on magnetic substrates such as Ni is important for spintronic device applications. Solid-state electrolytes (SSEs) are of significant interest for their promise as lithium-ion conducting materials but are prone to degradation due to lithium carbonate formation on the surface upon exposure to atmosphere, adversely impacting Li ion conduction. In situ XPS monitored changes in the composition of the SSE Li garnet (Li6.5La3Zr1.5Ta0.5O12, LLZTaO) upon annealing in UHV and upon Ar+ ion sputtering. Trends in core level spectra demonstrate that binding energy (BE) calibration of the Li 1s at 56.4 eV, yields a more consistent interpretation of results than the more commonly used standard of the adventitious C 1s at 284.8 eV. Annealing one ambient-exposed sample to >1000 K in UHV effectively reduced surface carbonate and oxygen, leaving significant amounts of carbon in lower oxidation states. A second ambient-exposed sample was subjected to 3 keV Ar+ ion sputtering at 500 K in UHV, which eliminated all surface carbon, and reduced the O 1s intensity and BE. These methods present alternative approaches to lithium carbonate removal than heating or polishing in inert atmospheres and are compatible with fundamental surface science studies. In particular, the data show that sputtering at mildly elevated temperatures yields facile elimination of carbonate and other forms of surface carbon. This is in contrast to annealing in either UHV or in noble gas environments, which result in carbonate reduction, but with significant remnant coverages of other forms of carbon.
