Weispfenning, M. and Zach, F. and Prettl, Wilhelm (1989) Effect of impact ionization on the saturation of 1s→2p+ shallow donor transition in n-GaAs. International Journal of Infrared and Millimeter Waves 9 (12), pp. 1153-1171.
The magneto-photoconductivity due to 1s-2p+ optical transitions of shallow donors in n-GaAs has been investigated as a function of intensity for several bias voltages at low temperatures between 2K and 4.2 K. At low intensities a superlinear increase of the photoconductive signal with rising intensity has been observed which gets more pronounced at higher bias voltages and lower temperatures. The ...
