High-temperature performance of gallium-nitride-based

2018-6-11  The temperature-dependent radiation-detection performance of an alpha-particle detector that was based on a gallium-nitride (GaN)-based pin structure was studied from 290 K to 450 K. Current–voltage–temperature measurements (I – V – T) of the reverse bias show the exponential dependence of leakage currents on the voltage and temperature.
