Abstract

Deep centers in as-grown and electron-irradiated n-GaN on sapphire have been characterized by deep level transient spectroscopy. Electron-irradiation (Elf) creates V-N-related centers with activation energy E-T=0.06 eV and a center with E-T=0.85 eV, which might be related to N-I. Deep centers in as-grown materials show a close connection with high dislocation densities and some of them indeed behave like "line-defects". Based on comparisons with El-induced centers, some deep centers in as-grown materials are identified as possible point defects.
