By employing non-equilibrium Green's function combined with the spin-polarized density-functional theory, we investigate the spin-dependent electronic transport properties of armchair arsenene nanoribbons (aAsNRs). Our results show that the spin-metal and spin-semiconductor properties can be observed in aAsNRs with different widths. We also find that there is nearly 100% bipolar spin-filtering behavior in the aAsNR-based device with antiparallel spin configuration. Moreover, rectifying behavior and giant magnetoresistance are found in the device. The corresponding physical analyses have been given.
