Abstract
Monolayer 2D material WSe2 provides an unique platform for exploring the generation and control of spin and valley polarization. In this work we conduct Kerr rotation measurements on monolayer WSe2 transisors to show the electrical control and temperature dependence of the spin and valley polarization generated by the spin and valley Hall effect (SVHE). A drift-diffusion theory along with the reflection spectra and electrcal IV curves are used to interpret the data and extract meaningful parameters.
