摘要

在原子层掺杂技术的帮助下，我们从理论上探索了如何利用δ电位来操纵基于自旋轨道耦合（SOC）调制磁性纳米结构的时空电子自旋分离器（TESS）。由于存在自旋轨道耦合，即使在 TESS 内嵌入了 δ 掺杂，停留时间仍然取决于电子自旋。此外，自旋极化率的大小和符号都可以通过调整δ掺杂的重量或位置来控制。因此，可以获得一种结构上可操控的 TESS 器件，用于半导体自旋电子器件的应用。

Manipulating dwell time and spin polarization via δ-doping for electrons in spin-orbit-coupling modulated magnetic nanostructure

With the help of atomic-layer doping technology, we theoretically explore how to use a δ-potential to manipulate a temporal electron-spin splitter (TESS), which is based on a spin-orbit-coupling (SOC) modulated magnetic nanostructure. Due to the SOC, the dwell time still depends on electron spins even if a δ-doping is embedded inside the TESS. Moreover, both the magnitude and sign of spin polarization ratio can be controlled by tuning the weight or position of the δ-doping. Therefore, a structurally manipulable TESS device can be obtained for semiconductor spintronic device applications.
