摘要：

For the first time we present the results of an analysis of the energy distribution function of 2D excitons for fixed nonequilibrium phonon spectra. The calculations are based on the kinetic equation for the interacting 2D exciton and 3D acoustic phonon gases. For the low-density exciton gas in GaAs/AlGaAs quantum wells (QW), we find a strong dependence of the exciton energy distribution on the QW width and nonequilibrium phonon spectrum.
