Abstract

A comprehensive theory is proposed to describe the polarization-dependent fine splitting of exciton doublet lines and the relation between the polarization direction and the energy level order of doublet states in anisotropic quantum dots. The extremely slow spin relaxation within exciton doublet states is predicted. At the same time, it is found that the cross-relaxation between orthogonally polarized exciton states is significant.
