论文摘要
丹尼单层SB的电子特性引起了极大的关注。在本文中，研究了扶手椅中的自旋运输抗氨基烯纳米替比（ASBNR）。按照紧密结合模型，我们通过非平衡绿色功能（NEGF）方法来计算传输概率和电导。探索了外部电场垂直到色带平面的影响。我们的结果表明，随着垂直电场的速度，自旋叉速率会增加。通过考虑存在带电杂质的存在来解决旋转转运的障碍影响。发现带电的杂质还提高了自旋闪光速率，但比平面外电场的程度较小。
The electronic properties of antimonene, single-layer Sb, are attracting great attention. In this paper, spin transport in armchair antimonene nanoribbon (ASbNR) is investigated. Following the tight-binding model, we calculate both the transmission probability and the conductance by means of the non-equilibrium Green's function (NEGF) method. The effects of an external electric field vertical to the ribbon plane are explored. Our results indicate that the spin-flip rate increases with the vertical electric field. Disorder effects on spin transport are addressed by considering the presence of charged impurities. It is found that charged impurities also enhance the spin-flip rate but to a lesser extent than the out-of-plane electric field.
