Effects of neutron on reverse bias characteristics of commercially available SI and gaas diodes

This study investigates the effects of neutron radiation on reverse bias characteristics of commercial silicon and gallium arsenide diodes. Reverse bias current-voltage and capacitance-voltage characteristics of the diodes were measured at room temperature before and after irradiation. The diodes we...
