We study the physical mechanisms of single event production in GaN wide-bandgap semiconductor subjected to atmospheric high-energy (> 1 MeV) neutron irradiation. The interactions of incident neutrons with the target material are investigated with Geant4 and the transport of the deposited charge simulated using our random-walk drift-diffusion (RWDD) modelling approach in a generic reversely biased bulk junction.
