Abstract

The mechanisms of energy and dephasing relaxation of quasi-two-dimensional excitons in quantum well structures are clarified for both the localized and delocalized excitons. The recently observed energy relaxation rate of the n = 1 heavy hole exciton and the energy and temperature dependences of the homogeneous linewidth (ρ_h) are explained quantitatively. The dependence of ρ_h on the quantum well thickness is predicted. The relaxation mechanisms of the higher lying (e.g., n = 2) exciton states are also discussed.
