Analyzing possible relaxation mechanisms in two-dimensional electron gas in GaAs-AlGaAs inverted structures we show that the existence of unintentional acceptor doping in the AlGaAs barriers, with concentration as high as 10 17 cm-3, provides the only explanation for the observed transport and single particle relaxation times.
