ABSTRACTWe have investigated a correlation between electronic deep levels and current collapses in AlGaN/GaN hetero-structures by capacitance-voltage and photo-capacitance spectroscopy techniques, using Schottky barrier diodes. Three specific deep levels located at ~2.07, ~2.80, ~3.23eV below the conduction band were found to be significantly enhanced for the severe current collapse. These levels probably originate in Ga vacancies and residual C impurities and are probably responsible for the current collapses of the AlGaN/GaN hetero-structures.
