摘要

A marked hysteresis was observed in C-T characteristics of GaN p-i-n diodes measured during heating/cooling cycles. The phenomenon is related to positive charging of deep traps located close to the p-n junction and having the concentration higher than about 1017 cm-3. Such recharging, via some not completely clear mechanisms, also effects the current-voltage characteristics increasing the reverse and the forward currents at low forward biases.
