摘要：

We report experimental and theoretical results on picosecond time resolved photoluminescence spectroscopy of 2D-excitons in multiquantum well structures. A theoretical model is formulated which includes the cooling of the free exciton gas by acoustical phonon emission and the localization of excitons due to interface defects. The cooling rate of 2D excitons is shown to be enhanced with respect to the 3D case. © 1991.
