Antisite defect qubits in monolayer transition metal dichalcogenides
Nature Communications, 2022 Two-dimensional materials offer a promising platform for scalable solid-state spin qubit. Here, using high-throughput ab initio simulations, the authors identify suitable defect centers in monolayer group-VI transition metal dichalcogenides and assess ...

Intervalley Scattering and Localization Behaviors of Spin-Valley Coupled Dirac Fermions [PDF]
, 2013 We study the quantum diffusive transport of multivalley massive Dirac cones, where time-reversal symmetry requires opposite spin orientations in inequivalent valleys. We show that the intervalley scattering and intravalley scattering can be distinguished

Exciton Relaxation Cascade in Two-dimensional Transition-metal dichalcogenides [PDF]
, 2017 Monolayers of transition-metal dichalcogenides (TMDs) are characterized by an extraordinarily strong Coulomb interaction giving rise to tightly bound excitons with binding energies of hundreds of meV. Excitons dominate the optical response as well as the

Thermal conductivity across transition metal dichalcogenide bilayers
iScience, 2022 Cross-plane thermal conductivities of transition metal dichalcogenide M X 2 (M = Mo, W; X = S, Se) bilayers are determined by homogeneous nonequilibrium molecular dynamics. The best insulator is found to be W S e 2 : W S e 2 , closely followed by W S 2 : W S 2 and M o S e 2 : W S e 2 .

Photocurrent generation in a metallic transition-metal dichalcogenide [PDF]
Physical Review B, 2018 Light induced current in two-dimensional (2D) layered materials emerges from mechanisms such as photothermoelectric effect, photovoltaic effect or nonlocal hot carrier transport. Semiconducting layered transition metal dichalcogenides have been studied extensively in recent years as the generation of current by light is a crucial process in ...

Inverted valley polarization in optically excited transition metal dichalcogenides
Nature Communications, 2018 In atomically thin transition metal dichalcogenides, spin- and valley-polarised states can be addressed thanks to large spin–orbit coupling and circular dichroism.
