Abstract

We develop a low-temperature theory of the resonant Raman scattering from a semiconductor quantum dot, whose electronic subsystem is resonant with the confined longitudinal-optical (LO) phonon modes. Our theory employs a generalized model for the quantum dot's energy spectrum renormalization, which is induced by the polar electron-phonon interaction. The model takes into account the degeneration of electronic states and allows for arbitrary LO-phonon modes to be involved in the vibrational resonance. We solve the generalized master equation for the reduced density matrix, in order to derive an analytical expression for the differential cross section of the resonant Raman scattering from a single quantum dot.
