We have derived a set of quantum balance equations suitable for the analysis of steady-state electronic transport in AlGaAs/GaAs heterojunctions. Initially, approximate semianalytical expressions for the subband wavefunctions, energy levels, and populations of the two-dimensional electron gas (2DEG) confined at the heterojunction interface are obtained, which are subsequently used in the calculation of the intra- and intervalley correlation functions of the 2DEG. The resulting force and energy balance equations are solved to yield drift velocities and electron temperatures of the electrons as a function of the applied electric field. Remote impurity, longitudinal optical phonon and intervalley phonon scattering are taken into account, as well as the nonparabolicity of the GaAs bandstructure.
