Abstract : Neutrons radiation effects on diode current-voltage characteristics have been studied for a variety of diodes over 1x10 to the 13th power to 3x10 to the 15th power n/sq cm 1 MeV equivalent neutron fluence range. A classification is proposed here for the first time. For constant forward current IF higher than that in the generation-recombination regime, the diode voltage VF either increases with fluence phi (Type 1 diode), or VF first decreases with phi at lower fluence levels and then increases with phi at higher fluence levels (Type 2 diode), or VF decreases with phi at all fluence levels used in this work (Type 3 diode).
