Abstract
We investigate theoretically the transport properties, including the transmission probability and conductance in a MoS2-based junction with time-periodic potential in the presence of intrinsic spin–orbit coupling. It is found that, unlike a graphene junction under time-dependent potential, the transmission probability depends on the valley degree of freedom and the sign of n for the nth sideband even at the normal angles of incidence. The transmission probability shows strong dependency on the amplitude of the time-periodic potential. Also, the transmission probability decreases for both valleys as the order of the sideband increases. The transmission probability decreases dramatically for larger angles of incidence. Moreover, it is found that the conductance for both valleys has a gap with respect to the static potential barrier height and it decreases as the sideband number increases.
