Coupled spin and valley physics in monolayers of MoS2 and other group-VI dichalcogenides.
TL;DR: It is shown that inversion symmetry breaking together with spin-orbit coupling leads to coupled spin and valley physics in monolayers of MoS2 and other group-VI dichalcogenides, making possible controls ofspin and valley in these 2D materials.
Journal ArticleDOI
Three-band tight-binding model for monolayers of group-VIB transition metal dichalcogenides
TL;DR: In this article, a three-band tight-binding model for describing low-energy physics in monolayers of group-VIB transition metal dichalcogenides is presented.
Journal ArticleDOI

TL;DR: In this article, optical studies of WS2 and WSe2 monolayers and multilayers were carried out, and it was shown that second harmonic generation shows a dramatic evenodd oscillation with the number of layers, consistent with the presence (absence) of inversion symmetry in even-layer (odd-layer).

TL;DR: The efficiency of second harmonic generation shows a dramatic even-odd oscillation with the number of layers, consistent with the presence (absence) of inversion symmetry in even-layer (odd-layer) and the giant spin-valley coupling which fully suppresses interlayer hopping at valence band edge near K points.
Journal ArticleDOI
Electronic structures and theoretical modelling of two-dimensional group-VIB transition metal dichalcogenides.
TL;DR: The bulk electronic structures of these new 2D TMD materials as well as the theoretical models developed at different levels are reviewed, along which the understanding of the origins of a variety of properties observed or predicted is sort out.
