Novel valley and spin physics in monolayer MoS$_{2}$

ORAL

Abstract

We show that the valley Hall effect and valley-dependent optical selection rule can be realized in monolayer MoS$_{2}$, which is a direct bandgap semiconductor with non-central valleys. In addition, spin-orbit coupling in this materials is large, which gives rise to novel spin physics tied to the valley degree of freedom.
