Degradation is a very important effect for devices made from A**I**I**IB**V compounds; major parts are played by dislocations and stress inhomogeneities, but the mechanism is not entirely clear. The authors have examined the behavior of deep levels associated with degradation in order to elucidate it. Further research has shown that a family of such deep levels can arise without substantial degradation, but in that case the spectra obtained by deep-level transient spectroscopy DLTS are very much dependent on the illumination, minority injection, and heat treatment. These levels have been detected here in a light-emitting diode.
