Abstract: Transition metal dichalcogenides (TMDCs) have been an important research subject, due to their unique electrical and optical properties, for the last decade or so. TMDCs have two distinct electronic band extrema with different electron spin states, +K and K valleys. Valley polarization was demonstrated by creating excitons at a specific valley using circularly polarized light of proper helicity. Furthermore, valley-polarized exciton transport, driven by thermal or chemical potential gradients, can exhibit valley-dependent transverse motion originating from the Berry curvature difference in +K and K valleys, which is known as exciton Hall effect. In this talk, I will present survey on valley polarization as well as exciton Hall effect and recent work on them in our lab.
