Abstract
708,449. Light-detecting devices. VOGT, A. Sept. 24, 1951 [Sept. 23, 1950], No. 22327/51. Class 40 (3). [Also in Group XXXVI] In a photo-electric cell, such as a barrier-layer cell, a surface of the metal electrode arranged to face incident light carries a dielectric layer of such thickness and refractive index that for light of a frequency at the middle of the frequency band to be transmitted or utilized, reflection between the air and the dielectric layer and between the dielectric layer and the electrode are arranged to offset one another by interference. The dielectric layer, which may be an oxide of silicon, a metallic fluoride, phosphide or sulphide, may be applied by evaporation, sputtering or chemical deposition, has a thickness of one quarter (or an odd number of quarters) of the wavelength of the middle frequency light and may comprise more than one dielectric material. The electrode may be of gold, silver, copper or a copper alloy.
