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.

Download or read book Exciton and Valley Properties in Atomically Thin Semiconductors and Heterostructures written by Kha Xuan Tran and published by . This book was released on 2019 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two dimensional van der Waals (vdW) materials recently emerged as promising candidates for optoelectronic, photonic, and valleytronic applications. Monolayer transition metal dichalcogenides (TMD) are semiconductors with a band gap in the visible frequency range of the electromagnetic spectrum. Their unique properties include evolution from indirect band gap in bulk materials to direct band gap in monolayers, large exciton binding energy (few hundred meV), large absorption per monolayer (about 10%), strong spin-orbit coupling, and spin-valley locking. Moreover, two or more TMD monolayers can be stacked on top of one another to create vdW heterostructures with exciting new properties. Optical properties of semiconductors near the band gap are often dominated by the fundamental optical excitation: the exciton (Coulomb-bound electron-hole pair). Excitons in TMD monolayers (intralayer exciton) exhibit a large binding energy and a very short lifetime. The excitons in TMD monolayers are formed at the boundary of the Brillouin zone at the K and K' points. The time-reversal symmetry dictates that spins are oriented with opposite directions, leading to distinct optical selection rules for the excitons at these two valleys, a property known as the spin-valley locking. Valley polarization is often characterized by circularly polarized photoluminescence (PL). We show that the degree of valley polarization in a WSe2 monolayer depends on the degree of disorder evaluated by the Stokes shift between the PL and absorption spectra. Intrinsic valley dynamics associated with different optical resonances can only be evaluated using resonant nonlinear optical spectroscopy. We discovered exceptionally long-lived intra-valley trions in WSe2 monolayers using two-color, polarization resolved pump-probe spectroscopy. A different type of excitons (interlayer excitons) may rapidly form in TMD heterostructures with a type-II band alignment. Because of the spatial indirect nature, interlayer excitons have a much longer lifetime, which is tunable by the twist angle between the two layers. Especially, we discover that multiple interlayer excitons formed in a small twist angle heterobilayer exhibit alternating circular polarization - a feature uniquely pointing to Moiré potential as the origin. We assign these peaks to the ground state and excited state excitons localized in a Moiré potential and explain how the spatial variation of optical selection rule within the moiré superlattice can give rise to multiple peaks with alternative circular polarization. The twist angle dependence, recombination dynamics, and temperature dependence of these interlayer exciton resonances all agree with the localized exciton picture. Our results suggest the feasibility of engineering artificial excitonic crystal using vdW heterostructures for nanophotonics and quantum information applications
