自旋弛豫:从2D到1D

Spin relaxation: From 2D to 1D

Alexander W. Holleitner

摘要:

在反转非对称半导体中,自旋-轨道相互作用产生非常有效的电子自旋弛豫机制。最近的工作,基于尺寸约束的D 'yakonov Perel'机制,描述了随着沟道宽度的减小,二维导电层的电子自旋弛豫时间增加。自旋弛豫的减慢可以理解为一维极限的前兆。

英文摘要:

In inversion asymmetric semiconductors, spin-orbit interactions give rise to very effective relaxation mechanisms of the electron spin. Recent work, based on the dimensionally constrained D'yakonov Perel' mechanism, describes increasing electron-spin relaxation times for two-dimensional conducting layers with decreasing channel width. The slow-down of the spin relaxation can be understood as a precursor of the one-dimensional limit.
