Spin transport features of the Al-doping zigzag-edged silicene nanoribbons (ZSiNRs) are investigated by using the nonequilibrium Green's function method and the spin-polarized density functional theory, where ZSiNRs are Si-H2 bonded at one edge while Si-H bonded at the other to form an asymmetric edge hydrogenation. It is found that a perfect spin filtering effect (100%) in such ZSiNRs can be achieved in the calculated bias region. The rectifying performance of spin-polarized currents with a ratio larger than 105 can be achieved by changing the...
