Probing Valley Dynamics in van der Waals heterostructures
Invited
Abstract
Van der Waals heterostructures composed of stacked atomically thin layers can exhibit novel phenomena due to the unique layer-layer interactions. In this talk, I will describe the observation of high-purity and long-lived valley polarization with microsecond lifetime in transition metal dichalcogenide heterostructures. I will also discuss spatially and temporally resolved imaging of pure valley and spin current in the WS2/WSe2 heterostructure.
