Abstract
Nonstoichiometric arsenic-rich GaAs grown at low temperatures by mbe (LT-GaAs) has been found to be semi-insulating after high-temperature annealing. The origin of this technologically important conversion is not yet fully understood. In order to study this effect, we performed photocurrent measurements on p-LT GaAs-n diodes in the spectral range between 0.75 eV and 1.5 eV. Thereby, we characterized EL2-like defects in annealed LT-GaAs.
