Silicene spintronics — A concise review |
Spin-filter based on the 4-ZSiNR. (a) Schematic model with one pair of gate electrodes on the two sides. (b) Spin-resolved transport spectrum under E gate = 0.3 V/Å. (c) Spin-resolved transmission eigenstate at E f and the Γ point in k -space under E gate = 0.3 V/Å. The isovalue is 1.0 a.u. (d) Spin-resolved transmission coefficient at E f k -space and spin filtration efficiency as a function of E gate. Reproduced with permission from Ref. [ 30 ].
