Monte Carlo simulation of electron transport in GaAs/Ga_1-xAl_xAs quantum wells using different phonon models

Abstract

We calculate electron-LO phonon intersubband and intrasubband scattering rates in a 70A GaAs/Ga,,AI,.,As quantum well considering the phonons to be described by the hydrodynamic model, the slab mode model and the bulk phonon approximation. These rates for the different phonon models are used in a Monte Carlo simulation of the electron drift velocity in the quantum well under the influence of an electric field
