In this paper, we report on thermostimulated electron emission experiments from resonant DX levels in bulk GaAlAs materials and in δ-doped GaAlAs/GaInAs/GaAs pseudomorphic heterostructures. To this end, the carriers were frozen out at low temperatur

We have developed Hall sensors featuring a two-dimensional electron gas (2DEG) in a AlGaAs/InGaAs/GaAs delta-doped heterostructure. They show a large sensitivity (750 V/A/T), a low thermal drift (-140 ppm//spl deg/C), an excellent linearity vs. magne

The results of magnetoconductivity measurements in GaInAs quantum wells are presented. The observed magnetoconductivity appears due to the quantum interference, which lead to the weak localization effect. It is established that the details of the wea
