What is Phonon emission by hot 2D electrons and holes in a Gallium Arsenide heterojunction: The influence of screening and acoustic anisotropy about?
The process of energy relaxation by phonon emission of hot two-dimensional electrons and holes in GaAs/AlGaAs heterojunctions has been studied using the heat-pulse technique for carrier temperatures below 40 K. To explain the experimental findings and to understand fully the process of electron-(or hole-) phonon coupling, theoretical calculations of the angular and polarization dependence of the emitted acoustic phonons were made. Phonon emission studies give detailed information concerning the phonon wave vector and polarization dependence of the emission process. This allows, in connection with the corresponding numerical simulations, interesting conclusions regarding the properties of the 2D carrier system itself (e.g. strength of carrier-phonon coupling constants, confinement of the 2D carriers perpendicular to the 2D system) to be reached.
