Dötzer, R. and Friedland, K. J. and Hey, R. and Kostial, H. and Miehling, H. and Schoepe, Wilfried (1994) Low-temperature electronic transport measurements on a gated delta -doped GaAs sample: magnetoresistance, quantum Hall effect and conductivity fluctuations. Semiconductor Science and Technology 9 (7), pp. 1332-1339.
We present magnetotransport measurements (up to 7 T) performed at very low temperatures (down to 20 mK) on a GaAs sample containing two parallel delta -doped layers whose carrier concentration can be varied by means of a gate electrode. With increasing negative gate voltage the resistance becomes more strongly temperature-dependent, indicating a more localized electron system. The ...
