Description
The measurement of spectral dependence of photoconductivity permits to investigate the deep level spectrum, recombination at the surface and photoelectric quantum yield.
This presentation deals with observation of an increase of quantum yield at lover photon energy in highly irradiated Si in comparison with less or non-irradiated Si. The effect was observed in neutron irradiated Si to the fluence 1e16 cm-2 and higher. It is attributed to the impact ionization via deep levels.
