Abstract

The measurement of the alloy scattering of two-dimensionally (2D) confined electrons in Al_xGa_1-xAs in the dilute Al concentration limit was discussed. The alloy scattering found to be independent of the temperature below 4.2 K and and a scattering rate of 35 ns^-1 per 1% Al impurities was obtained. The determination of alloy scattering potential was also elaborated.
