摘要：

The electron-optical-phonon scattering rates in GaAs/AlAs quantum wells (QW) are calculated on the basis of a fully microscopic description of the phonon spectrum. The results indicate the great importance of confined as well as GaAs-like and AlAs-like interface phonons. The implications of these findings are discussed by using the calculated rates in Monte Carlo simulations of ultrafast carrier relaxation in a 50 angstrom QW.
