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