Abstract
The effect of intra sub-band scattering by LA phonons on the dc field transport properties of electrons in quasi – 2D semiconductors is investigated using Phonon Boltzmann Transport Equation (PBTE), within the frame work of a simple theoretical model n which acoustic attention (amplification) effects are studied. The model assumes the electrons distribution is a displaced Fermi function with scattering confined to LA phonons which are in intimate contact with 2D-electron gas. The numerically calculated dependence of attenuation coefficient on phonon wave vector and quantum well width are shown and discussed.
