Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Two-dimensional (2D) transition metal dichalcogenides (TMDs), because of their sizable direct band gap, ultrathin body, good electron mobility, and versatile electronic structures, have attracted a lot of attention. They have shown their potential in future electronic, optoelectronic, photovoltaic, phase change, and photocatalytic devices. To examine their applicability to these devices, understanding their fundamental electronic structure and structural stability is a prerequisite. A systematic study of the electronic structure of monolayer transition metal dichalcogenides (TMDs) is performed by the density functional theory (DFT) method. Their band alignments are summarized and several representative bilayer heterostructures of two types of monolayer TMDs are investigated to understand the band realignment in the process of stacking. A formula is developed to predict the band realignment in the TMD bilayer heterostructure. Different to graphene, there exist several polymorphs of the same TMDs (e.g., 2H-MoTe2 and 1T-MoTe2). The total energies of various phases of TMDs are compared to determine the most energetically favorable phase. The electronic structure of TMDs, depending on the phase, can vary from metallic to semiconducting. This characteristic correlation between atomic and electronic structures opens up the possibility of controlling the electrical property by phase engineering, external field or charging. The charge-driven phase transition in monolayer WxMo1-xTe2 alloy has been investigated. Critical charge concentration and composition to induce phase transition is investigated. Doping, as an important technique of modulating the electronic properties of semiconductors, has been also investigated by DFT in monolayer MoS2. Substitutional doping of halogen group elements and nitrogen group elements is found to introduce n-type and p-type doping, respectively. The reduced dielectric screening will affect the exciton binding energy in 2D TMDs which will further change the impurity levels. NO2 adsorption-doping at the surface of monolayer WSe2 is also investigated showing p-type doping characteristic on WSe2. These findings have enabled the utilization of two-dimensional TMDs in the realization of future electronic devices.

This book was released on 2015 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two-dimensional semiconductors have long been studied for their unique optical and electronic properties, but with the work of Novoselov and Geim on van der Waals materials, two-dimensional semiconductors have seen a surge of renewed interest. This dissertation focuses on monolayer transition metal dichalcogenides (TMDCs), a class of two-dimensional materials that can easily be fabricated by mechanical exfoliation, much like graphene. In their bulk form, these materials have indirect band gaps, but transition to direct gap semiconductors in the monolayer limit. The band-edge optical response of TMDCs, like WSe2 and MoS2, is dominated by exciton absorption occurring at the ±K-points of the Brillouin zone. Because of the unique electronic structure of these materials, these two points form distinct valleys in the band structure which can be exploited to produce valley polarization. Exciton quantum dynamics are characterized by two fundamental parameters, one of which is the dephasing rate, [gamma], which describes quantum dissipation arising from the interaction of the excitons with their environment (i.e. other excitons, impurities, etc...). This dissertation focuses on measuring the fundamental property of dephasing time (which is inversely proportional to the dephasing rate and homogeneous linewidth) in monolayer WSe2 through the use of two-dimensional coherent spectroscopy. Our measurements have revealed a homogeneous linewidth consistent with dephasing times in the sub-picosecond regime. We also characterize the role of exciton-exciton and exciton-phonon interactions, on the homogeneous linewidth, through excitation density and temperature dependent studies. These studies have revealed strong many-body effects and nonradiative population relaxation as the primary dephasing mechanisms. Microscopic calculations show that in perfect crystalline samples of monolayer TMDCs, the radiative lifetimes are also in the sub-picosecond regime due to the large oscillator strengths inherent in these materials. This result is consistent with the short dephasing times found experimentally.
