ABSTRACT:
This invention relates to a process for producing a photoelectric detector of the high-gain photoresistor type comprising on a substrate an active layer of doped gallium arsenide provided with two electrodes with ohmic contacts for connection to a user circuit, said process consisting in applying to the active layer a treatment producing a selective attack of the surface of said layer modifying its degree of compensation in gallium and in arsenic and the superficial charge states.
