Abstract
- The spin-resolved transport for monolayer MoS2 through a zigzag nanoribbon superlattice based on the transfer matrix method in the resonant tunneling regime is investigated in the presence of an external perpendicular electric field. The controllable external electric field leads to the so-called Rashba effect, which can modulate the internal spin–orbit coupling. Our investigations show that by controlling the Rashba strength, it is possible to attain 100% spin-polarization and spin-flip, which can be used in designing an optimized spintronic device. In addition, the effects of superlattice specific parameters (D/W), the barrier height (V0), and the number of barriers (N) on the functionality of the system are studied, leading to optimum results for the case of 20 barriers.
