Exciton Relaxation Cascade in Two-dimensional Transition-metal dichalcogenides [PDF]

open access: yes, 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

open access: yesiScience, 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]

open access: yesPhysical 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

open access: yesNature 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.
