Patent GB-1127436-A (GB)
Title: Improvements in and relating to methods of detecting radiation
IPC: H01L31/103
Filed: 1965-10-12
Abstract: 1,127,436. Photo-electric arrangements. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Oct. 12, 1965 [Oct. 15, 1964], No. 43212/65. Heading G1A. [Also in Division H1] A radiation detector comprises a photo-sensitive semi-conductor body with capture centres in the forbidden band for both holes and electrons, and a source of auxiliary radiation capable of producing hole-electron pairs in the body. The capture centres cause the photo-current to be superlinearly related to the auxiliary radiation intensity within the intensity range in which the detector is operated. Sharp changes in current occur when the body is illuminated with radiation capable of modifying the population of the capture centres. The super-linear relationship is due to saturation of either the electron or the hole capture centres 11 and 12 respectively (Fig. 2). When centres 11 are the first to saturate, radiation capable of raising electrons from them into the conduction band increases the current while that capable of transferring them from the valance band to centres 12 decreases the current. If the centres 12 saturate first the effect of such radiation on the current is reversed. The auxiliary source is preferably an injection recombination source e.g. a zinc activated P type gallium phosphide wafer with a tin alloyed junction in the same body. In an opto-electronic switch using the detector both the auxiliary source and the source of radiation to be detected may be housed in the common envelope or formed in the same body as the photo-sensitive element. A recombination source consisting of a zinc and oxygen activated P type gallium phosphide wafer with an alloyed tin rectifying contact or of gallium arsenide may in this case provide the radiation to be detected.
