Abstract

The photoluminescent spectra from high-quality GaAs crystals grown from the vapour phase reveal a dominant Zn acceptor and a C acceptor, as well as an acceptor that would appear to have a smaller binding energy than C. We show that this shallowest acceptor is not a discrete chemical acceptor, having a smaller binding energy than C, but is rather due to a complex centre.
