The interaction of excitons with rough surfaces and its effect on light scattering spectra were investigated theoretically. We have employed a model for the excitonic surface potential based upon the generalized Morse potential, taking into account its random fluctuations, produced by the surfaсe roughness. Applying first-order perturbation theory, we calculate the cross section of light scattering from a rough GaAs surface and analyze its frequency dependence in the presence of an extrinsic surface-potential well with excitonic bound states.
