Effects on electrical characteristics of commercially available Si and GaAs diodes exposed to Californium-252 radiation

The aim of this research is to investigate the effects of neutron irradiation using Cf-252 neutron source on different types of commercially available Si and GaAs diodes. Pre and post irradiation effects are compared by analyzing their respective forward bias (FB) and reverse bias (RB) current-volta...
