Abstract
Studies have been made of the effect of nonequilibrium phonons on the population of coupled exciton states in GaAs/(AlGa)As double quantum w ells (DQWs) with very similar widths. Comparison of luminescence spect ra from the DQWs measured in the presence of nonequilibrium phonons wi th the spectra obtained in thermal equilibrium shows that the changes in exciton population induced hy phonons could either be due to phonon -assisted tunnelling or to exciton heating.
