Abstract: Kinetics of electrons occupying two subbands in a quantum well in the presence of a high in-plane accelerating electric field is studied taking into account optical-and acoustic-phonon scattering and scattering via resonance quasi-stationary states associated with shallow donors. Resonance scattering is analyzed in the context of the well-known Breit–Wigner model. The distribution function is constructed using the “random-walk” Monte Carlo method. Resonance-state scattering leads to the accumulation of electrons in the vicinity of the resonance state and, in general, to a considerable modification of the streaming-regime distribution function. The dependence of relative occupancies of the two subbands on the lattice temperature is determined.
