Resumen:
In the present work, a complete numerical analysis
of the influence of deep-trap levels on the dark current
of silicon PIN photodiodes under 1 MeV neutron
radiation was done. Results corroborate that energy
levels near the mid-gap affect to a great extent the
dark current. Radiation tolerances of undoped and
gold-doped devices were compared through
simulations. It has been concluded that gold in silicon
reduces the neutron-induced damage. Finally, a model
to calculate the dark current of irradiated devices
doped with deep-impurities is presented.
