  • Abstract
    Al0.27Ga0.73N/GaN HFETs were electron irradiated at ~ 80 K. The gate leakage and transistor current were measured and compared to theoretical tunneling models. The results are consistent with previous work but explicitly show that radiation produces point defects in the AlGaN that are positively charged at low temperature.
