Abstract
Anomalously large photoresponse to radiation of energies between about 2.8 eV and about 3.8 eV has been observed in certain gallium phosphide photodetectors having an 'as-grown' surface. This photoresponse is believed to be due to the low density of recombination centers in the as-grown surface.
