NIEL: Bulk Damages
compensation (d) of donators or acceptors
results in change of majority carriers and the effective doping concentration
direct impact on depletion depth and on the sensitive volume of a pn-junction
donator and acceptor-like defects are deactivated and at the same time acceptor like levels are created (prop. to the fluence)
type inversion 1.2 1012 1MeV equivalent neutrons
field gradient in pn-junction inverses (as well as the spreading direction)
because of their large depletion depth (hundreds of microsns) detector diodes are very sensitive to bulk damage
