Relaxation of the Electron Spin in Quantum Dots Via One- and Two-Phonon Processes
arXiv:cond-mat/0609108 · doi:10.1016/j.jmmm.2007.03.174
Abstract
We have studied direct and Raman processes of the decay of electron spin states in a quantum dot via radiation of phonons corresponding to elastic twists. Universal dependence of the spin relaxation rate on the strength and direction of the magnetic field has been obtained in terms of the electron gyromagnetic tensor and macroscopic elastic constants of the solid.
