| 摘 要： | 采用转移矩阵法,我们研究了在偏压存在的情况下,由沉积在InAs半导体异质结上的两条铁磁条带和一条肖特基金属条带构建的电子自旋过滤器中电子的自旋过滤特性.研究发现,该电子自旋过滤器中,电子自旋极化的大小和幅度与偏压密切相关,这些有趣的性质对如何制造一个偏压可调的电子自旋过滤器十分有益.

| Abstract: | Based on transfer-matrix method, we investigate the effect of bias on electron-spin polarization in the spin filter, which can be experimentally realized by depositing two ferromagnetic (FM)strips and a Schottky metal (SM) stripe in parallel configuration on top of the heterostructure. We find that both magnitude and sign of the electron-spin polarization are sensitive to the applied bias in this spin filter, which can result in a bias-tunable spin filter. |
