Exciton fine structures and spin relaxation in semiconductor quantum dots

Research output: Chapter in Book/Report/Conference proceedingChapter

Abstract

A comprehensive model is proposed to describe the polarization-dependent fine splitting of exciton doublet lines and their relative intensity ratio and the general aspects of spin relaxation in quantum dots (QD). The spin relaxation of QDs is computed by the energy levels including the spin-orbit interaction, the electron-hole exchange interaction and also the coupling between the conduction band and the valence band, if necessary and to estimate the relaxation rate induced by the electron-phonon interactions.
