β¦ Synopsis
Hot-electron transport in a AIGaAs/GaAs quantum well system is simulated using Monte Carlo techniques and the dependence on doping density in the AIGaAs is explored, taking into account electronelectron scattering. The appearance of a scattering-induced ndr over a range of doping densities, previously suggested on the basis on simple models, is confirmed.

In this work we investigated the optical control of the bidimensional electron gas density in a single asymmetric quantum well using, for the first time, photoreflectance. We performed our measurements at 80 and 300 K as a function of the power density of the pump beam. Under strong illumination, th
