摘要：

We calculate electron-LO-confined-phonon scattering rates in GaAs-AlGaAs quantum wells considering the influence of nonparabolicity on the energy subbands. We find that the subband nonparabolicity increases the scattering rates significantly for all transitions and that this effect is more pronounced as transitions from higher subbands are involved.
