This thesis demonstrates that layered heterostructures of two-dimensional crystals graphene, hexagonal boron nitride, and transition metal dichalcogenides provide new and interesting interlayer transport phenomena. Low-energy electron microscopy is employed to study the surface of atomically thin WSe2 prepared by metal-organic chemical vapor deposition on epitaxial graphene substrates, and a method for unambiguously measuring the number of atomic layers is presented. Using very low-energy electrons to probe the surface of similar heterostructures, a relationship between extracted work function differences from the layers and the nature of the electrical contact between them is revealed. An extension of this analysis is applied to surface studies of MoSe2 prepared by molecular beam epitaxy on epitaxial graphene. A large work function difference is measured between the MoSe2 and graphene, and a model is provided which suggests that this observation results from an exceptional defect density in the MoSe2 film. The thesis expounds a theory for computing tunneling currents between two-dimensional crystals separated by a thin insulating barrier; a few situations resulting in resonant tunneling and negative differential resistance are illustrated by computed examples, as well as observed characteristics, for monolayer and bilayer graphene tunneling junctions and transistors.

This book focuses on angle-resolved photoemission spectroscopy studies on novel interfacial phenomena in three typical two-dimensional material heterostructures: graphene/h-BN, twisted bilayer graphene, and topological insulator/high-temperature superconductors. Since the discovery of graphene, two-dimensional materials have proven to be quite a large “family”. As an alternative to searching for other family members with distinct properties, the combination of two-dimensional (2D) materials to construct heterostructures offers a new platform for achieving new quantum phenomena, exploring new physics, and designing new quantum devices. By stacking different 2D materials together and utilizing interfacial periodical potential and order-parameter coupling, the resulting heterostructure’s electronic properties can be tuned to achieve novel properties distinct from those of its constituent materials. This book offers a valuable reference guide for all researchers and students working in the area of condensed matter physics and materials science.

Today's data-driven applications, such as big data analytics, neural networks, and machine learning, require huge memory and computing resources. The latency and energy incurred for data movement between processing unit and memory has become a significant limitation (known as the "memory wall") as traditional techniques such as caching are no longer effective for the data-intensive applications that dominate modern computing. Solving the "memory wall" problem requires future computer technology to directly integrate memory and transistor devices with high density vertical interconnect accesses (vias) to provide parallel, high bandwidth memory access. However, the high temperature of silicon processing is not compatible with this 3D monolithic integration. A desired low temperature integration can be achieved by using two-dimensional (2D) materials which have intrinsically layered and flat atomic structures, because devices made of 2D materials can be fabricated at lower temperatures. This thesis introduces three exploratory studies on advancing 2D materials for developing 3D monolithic integrated systems. First, I focused on improving transistor performance and studied high-mobility 2D material black phosphorous (BP) transistors using various metals as the contact metal. This work achieved unipolar n-type BP transistors by using ultra-low work function metals, demonstrating record high n-type current. Furthermore, the study revealed the physical mechanisms of controlling doping and de-pinning effects for n- and p- type BP transistors. Beyond transistor studies, I then demonstrated the first 3D sequential monolithic integrated two levels of 1-transistor-1-resistor (1T1R) memory cells. The cell is fabricated entirely using 2D materials: hexagonal-Boron Nitride (hBN) serves as the resistive switching memory cell and monolayer Molybdenum Disulfide (MoS2) serves as the channel material for the transistor selector. In order to achieve a high-density memory array, a two-terminal selector with a high nonlinear current-voltage characteristic is necessary. I developed a new two-terminal selector utilizing a 2D material heterostructure with an H-shape energy barrier. This new device design in theory should have high on-state current density and virtually unlimited endurance due to its quantum tunneling mechanism. Our results characterized the first out-of-plane current through an ultra-thin (3 monolayer) heterojunction and provide the critical foundation for a high endurance selector using a 2D heterojunction. Due to the transferable feature of 2D materials, these processes can be easily adopted for 3D monolithic integrated transistors and memories in multiple logic and memory layers connected vertically by fine-grained nanoscale vias, thereby overcoming the "memory wall.".

This book summarizes the current status of theoretical and experimental progress in 2 dimensional graphene-like monolayers and few-layers of transition metal dichalcogenides (TMDCs). Semiconducting monolayer TMDCs, due to the presence of a direct gap, significantly extend the potential of low-dimensional nanomaterials for applications in nanoelectronics and nano-optoelectronics as well as flexible nano-electronics with unprecedented possibilities to control the gap by external stimuli. Strong quantum confinement results in extremely high exciton binding energies which forms an interesting platform for both fundamental studies and device applications. Breaking of spatial inversion symmetry in monolayers results in strong spin-valley coupling potentially leading to their use in valleytronics. Starting with the basic chemistry of transition metals, the reader is introduced to the rich field of transition metal dichalcogenides. After a chapter on three dimensional crystals and a description of top-down and bottom-up fabrication methods of few-layer and single layer structures, the fascinating world of two-dimensional TMDCs structures is presented with their unique atomic, electronic, and magnetic properties. The book covers in detail particular features associated with decreased dimensionality such as stability and phase-transitions in monolayers, the appearance of a direct gap, large binding energy of 2D excitons and trions and their dynamics, Raman scattering associated with decreased dimensionality, extraordinarily strong light-matter interaction, layer-dependent photoluminescence properties, new physics associated with the destruction of the spatial inversion symmetry of the bulk phase, spin-orbit and spin-valley couplings. The book concludes with chapters on engineered heterostructures and device applications such as a monolayer MoS2 transistor. Considering the explosive interest in physics and applications of two-dimensional materials, this book is a valuable source of information for material scientists and engineers working in the field as well as for the graduate students majoring in materials science.
