چکیده انگلیسی
Based on density functional theory combined with nonequilibrium Green's function method, we have investigated the spin-polarized transport properties of the (2Â ÃÂ 1) reconstructed zigzag MoS2 nanoribbon (ZMoS2NR)-based devices. The results show that these devices can exhibit multiple high-performance spin-dependent transport properties by modulating the applied magnetic field, including spin-filtering, negative differential resistance and giant magnetoresistance effects. These effects are explained by the spin band structures around the Fermi level, as well as their symmetries. Moreover, all effects are robust regardless of the nanoribbon width. These findings suggest the (2Â ÃÂ 1) reconstructed ZMoS2NRs have great potential in the field of spintronics.
