摘要：
We have measured the lifetime of electronic intersubband excitations by emission of longitudinal optical phonons in GaAsAlGaAs quantum wells using time-resolved anti-Stokes inelastic light scattering. We find the lifetime of electrons in the n=2 level of a 146 Å well to be ≤ 1 ps which is in excellent agreement with theoretical calculations of two-dimensional electron-phonon interactions. © 1990.
