Research output: Chapter in Book/Report/Conference proceedingConference contribution


We demonstrate a new optoelectronic platform using WSe2-Bi2Se3 heterostructures to generate and detect the valley-coupled spin-polarized photocurrents at room temperature. The light polarization and the external electric field can manipulate the magnitude of the current.
