Chi-Shung Tang, Yun-Hsuan Yu, Nzar Rauf Abdullah, Vidar Gudmundsson

摘要:

我们提出了一个利用垂直强Rashba自旋轨道和塞曼场的非铁磁量子信道中的单模自旋注入方案。通过施加一个积极的顶栅电位,以注入电子从自旋轨道间隙的低能量制度,我们观察到相干破坏的传输签名的类空穴准束缚态,类电子准束缚态,或类空穴束缚态的功能,是敏感的选择沿传输方向的顶栅长度。

英文摘要:

We suggest a single-mode spin injection scheme in non-ferromagnetic quantum channels utilizing perpendicular strong Rashba spin-orbit and Zeeman fields. By applying a positive top-gate potential in order to inject electrons from the spin-orbit gap to the low-energy regime, we observe coherent destruction of transport signatures of a hole-like quasi-bound state, an electron-like quasi-bound state, or a hole-like bound state features that are sensitive to the selection of the top-gate length along the transport direction.
