A microscopic analysis of exciton formation and relaxation in photoexcited quantum wells is presented. The theoretical approach is based on a Monte Carlo simulation of the coupled free-carrier and exciton dynamics, and includes various mechanisms contributing to exciton formation and relaxation. Our investigation clarifies the ori,ain of excitonic luminescence in time-resolved experiments. In particular, we address the problem of the relative efficiencies of exciton formation assisted by either LO phonons or acoustic phonons, respectively.

Abstract

A microscopic analysis of exciton formation and relaxation in photoexcited quantum wells is presented. The theoretical approach is based on a Monte Carlo simulation of the coupled free-carrier and exciton dynamics, and includes various mechanisms contributing to exciton formation and relaxation. Our investigation clarifies the ori,ain of excitonic luminescence in time-resolved experiments. In particular, we address the problem of the relative efficiencies of exciton formation assisted by either LO phonons or acoustic phonons, respectively.
