CATHODOLUMINESCENCE STUDIES OF ELECTRON INJECTION-INDUCED EFFECTS IN HI-NITRIDES

摘要

The effect of electron injection in p-type Metal Organic Chemical Vapor Deposition GaN was studied using variable temperature cathodoluminescence. The activation energy for the effect, found from cathodoluminescence measurements, is ～ 190 meV, which is close to the thermal ionization energy of the Mg-acceptor.
