Intersubband phonon overlap integrals for AlGaAs/GaAs single-well heterostructures

Abstract

The five lowest subband coupling coefficients $H_{\mathrm{mn}}$(Q) are calculated for polar-optical-phonon scattering in ${\mathrm{Al}}_{0.3}$ ${\mathrm{Ga}}_{0.7}$As/GaAs single-well heterostructures. The wave functions are calculated self-consistently within the effective-mass approximation including exchange and correlation effects.
