The electrical model that ionizing radiation reduces the effective power output of GaN-based blue light-emitting diode is proposed by investigating the light/dark current generation mechanism in active region of GaN-based blue light emitting diode device under ionizing irradiation. The model that the ionizing radiation increases the 1/f noise of GaN-based blue light-emitting diode device is proposed by studying the 1/f noise mechanism of the active region of GaN-based blue light-emitting diode device under ...
