摘要：

Disorder-induced Rayleigh scattering of excitons in quantum wells is investigated theoretically. For classical excitons (long-range spatial correlation), the disorder average can be performed exactly. For the full problem, a kinetic equation with ''weak memory'' for the exciton distribution is derived which coincides with the classical result in the appropriate limit. The theoretical results are compared with recent experimental data on femtosecond time-resolved luminescence explaining well the finite rise time and the heavy-light-hole beating.
