Abstract

Spin/valley dependent dwell time in 8-Pmmn borophene junction under Rashba spin–orbit interaction (RSOI) is studied. The dwell time as well as transmission probability for incident electrons with spin-up show a different behavior than the incident electrons with spin-down, and these quantities can be controlled effectively by the junction direction, incident angle, the RSOI strength and the barrier width. Also, the dwell time is dependent on the degree of freedom of the valley and shows oscillating behavior with the increase of the barrier width. The spin polarization and spin filtering in 8-Pmmn borophene junction under RSOI can be obtained in the time domain.

8-Pmmn 硼吩结中与自旋/谷值相关的停留时间

研究了拉什巴自旋轨道相互作用（RSOI）下 8-Pmmn 硼吩结中与自旋/谷相关的驻留时间。自旋上升的入射电子的驻留时间和传输概率与自旋下降的入射电子的驻留时间和传输概率表现出不同的行为，这些量可以通过结方向、入射角度、RSOI 强度和势垒宽度进行有效控制。此外，驻留时间还取决于谷的自由度，并随着势垒宽度的增加而呈现振荡行为。在时域中可以得到 RSOI 作用下 8-Pmmn 硼吩结中的自旋极化和自旋滤波。
