量子点中空穴自旋的双声子弛豫

Relaxation of hole spins in quantum dots via two-phonon processes

Mircea Trif, Pascal Simon, Daniel Loss

摘要:

本文从理论上研究了低磁场下重空穴量子点的自旋弛豫。我们证明了双声子过程和自旋轨道相互作用是实验相关的,并提供了一个解释最近观察到的饱和的自旋弛豫率在重空穴量子点与消失的磁场。我们建议进一步的实验,以确定相关的自旋弛豫机制在低磁场。

英文摘要:

We investigate theoretically spin relaxation in heavy hole quantum dots in low external magnetic fields. We demonstrate that two-phonon processes and spin-orbit interaction are experimentally relevant and provide an explanation for the recently observed saturation of the spin relaxation rate in heavy hole quantum dots with vanishing magnetic fields. We propose further experiments to identify the relevant spin relaxation mechanisms in low magnetic fields.
