Gallium Arsenides - an overview | ScienceDirect Topics
Gallium arsenide can be made semi-insulating and photorefractive through use of the stoichiometry-related EL2 center (Klein, 1984) or by doping with chromium (GaAs:Cr) (Glass et al., 1984). The growth technology for GaAs is arguably the most advanced of all the compound semiconductors; however, photorefractive quality can vary considerably ...
