Polaron model in self-assembled InAs/GaAs quantum dots— A perturbative approach

Abstract

We propose an analytic study of the polaron spectrum in self-assembled InAs/GaAs quantum dots. The approach is based on the first-order degenerate perturbation theory and, therefore, it allows us to describe the one-phonon processes. In such framework, we are able to interpret recent experimental findings obtained by magneto-far-infrared and Raman spectroscopy.
