Monte Carlo simulations of hot electron transport in AlGaAs/GaAs /AlGaAs quantum wells were carried out in order to clarify the drift velocity overshoot and steady state drift velocity versus the electric-field relation. In the simulations, we took into account the nonparabolic isotropic energy band structures. Results are given for GaAs well widths of 500 and 100 Å and an electron sheet density of 1.0×1012cm-2at 77 K. The drift-velocity overshoot reaches about 7×107cm/s at an electric field of 10 kV/cm in both quantum well structures. A negative differential mobility appears beyond 3 kV/cm in both structures due to electron transfer from the Γ valley to theLvalleys.
