Realization of valley-spin polarized current via parametric pump in monolayer $\mathrm{Mo}{\mathrm{S}}_2$

Kai-Tong Wang, Hui Wang, Fuming Xu +2

Monolayer $Mo{S}_2$ is a typical valleytronic material with valley-spin locked valence bands. We numerically investigate the valley-spin polarized current in monolayer $\mathrm{Mo}{\mathrm{S}}_2$ vi…
