Abstract

1,224,171. Gunn effect devices. ASSOCIATED SEMICONDUCTOR MFRS. Ltd. 5 Feb., 1968 [7 Feb., 1967], No. 5718/67. Addition to 1,161,782. Heading HlK. A voltage tunable planar Gunn-effect device has ohmic cathode and anode contacts disposed on or adjacent one face of a laminar semiconductor body or layer, the relative disposition and shape of the electrodes being such that the field between them in the quiescent state is non- uniform. A preferred device comprises a 0 ohm. cm. GaAs layer 3Á thick epitaxially deposited on a 30Á semi-insulating GaAs plate with concentric circular and annular contacts disposed in etched cavities extending into the layer or through it to the substrate, the inner contact being 10Á in diameter and the internal diameter of the annular contact being 40Á. The contacts may consist of tin, or a gold-tin, silvergold-germanium, gold-indium-germanium or silver-indium-germanium alloy or of a goldgermanium alloy coated with nickel. In other embodiments the inner edge of one contact is jagged or arcuate while the other may be straight, arcuate or jagged. Indium phosphide and cadmium telluride may be used instead of gallium arsenide. Reference has been directed by the Comptroller to Specification, 1,170,984.
