摘要:

研究了双指门控制的具有Rashba-Zeeman(RZ)子带能隙的n型量子信道中的自旋分辨共振输运性质。通过适当地调整DFG在强Rashba耦合制度,共振态结构的电导可以发现,是敏感的DFG系统的长度。此外,在RZ带隙以下的类空穴束缚态特征和在上自旋分支的阈值处的类电子准束缚态特征可以被发现,这对DFG系统的长度不敏感。

英文摘要:

We investigate double finger gate (DFG) controlled spin-resolved resonant transport properties in an n-type quantum channel with a Rashba-Zeeman (RZ) subband energy gap. By appropriately tuning the DFG in the strong Rashba coupling regime, resonant state structures in conductance can be found that is sensitive to the length of the DFG system. Furthermore, a hole-like bound state feature below the RZ gap and an electron-like quasi-bound state feature at the threshold of the upper spin branch can be found that is insensitive to the length of the DFG system.
