Abstract
We give an overview of experiments in which luminescence detection of nonequilibrium phonons in semiconductors is used to study the interact ion of acoustic phonons with two-dimensional excitons. Questions which are specific for the 2D exciton-phonon interaction are discussed: mom entum conservation in the exciton-phonon interaction; role of exciton- exciton collisions; drag of 2D excitons by phonons; 2D excitons as a p honon spectrometer.
