ABSTRACTWe present a density-matrix approach for the description of nonequilibrium carrier dynamics in optically excited semiconductor quantum dots, that explicitly accounts for exciton-exciton as well as exciton-carrier interactions. Within this framework, we analyze few-particle effects in the optical spectra and provide a consistent description of additional peaks appearing at high photoexcitation density. We discuss possible applications of such optical nonlinearities in future coherent-control experiments.

A theory of photoluminescence and Raman scattering in semiconductor quantum dots is developed, which relies on two key ingredients. First, it takes into account non-adiabaticity of the exciton-phonon system. Second, it includes a multimode dielectric model of LO-phonons and of the electron-phonon interaction in confined systems. Our approach is applied to calculate the optical spectra of several quantum-dot structures: ensembles of spherical CdSe, CdSe x S 1-x and PbS quantum dots, self-assembled InAs/GaAs and CdSe/ZnSe quantum dots, brick-shaped InAs/GaAs quantum dots created by local anodic oxidation using the atomic force microscope.
