Abstract: Effect of the reactor fast neutron flux (E = 2 MeV, = 2⋅1014 n/cm2) on the current-voltage, capacitance-voltage characteristics, the electroluminescence intensity of power nGaN/GaN LEDs on the SC and AuSn/Si substrates are studied. It was revealed that radiation hardness of InGaN/GaN heterostructures depend on the substrate.

Keywords: nGaN/GaN light emitting diode, irradiation, current-volt characteristic.
