We calculate the electronic states, the ionized-donor concentrations, the Q2DEG and the bulk-electron concentrations and the corresponding mobilities as a function of temperature. Our numerical results are in very good agreement with the experimental data.</style></abstract><notes><style face="normal" font="default" size="100%">cited By 6</style></notes></record></records></xml>
