Abstract

The neutron irradiation effects in GaN-based double heterojunction (DH) light-emitting diodes (LEDs) are investigated. Both optical and electrical properties showed significant degradation after neutron irradiation. The basic mechanisms responsible for both electrical and optical degradation are discussed. Some optical and electrical recovery due to an injection-enhanced annealing effect is observed in our irradiated LEDs.
