Abstract
Abstract A self-powered electronic component, particularly, a Josephson junction, is formed of a layer of a superconductor epitaxially grown on a substrate formed of a single crystal of silicon. In accordance with one embodiment of the invention, the expitaxial superconductor layer is separated into two parts by a groove defined by a thin growth region, forming the Josephson junction. On the epitaxial layer at the first side of the junction is deposited a thin layer of an insertion material forming the positive pole of the Josephson junction as well as the cathode of a solid state power generator. On the epitaxial layer and over the thin layer of insertion material is deposited a separator, or fast ion conductor, which assumes the weak link of the Josephson junction as well as separates the ion source from the electronic exchanger and assumes the fast ion transport. A thin film of material, such as Lithium, providing an ion source and forming the anode of the junction, is deposited over the Josephson junction, covering the separator and extending into contact with the opposite side of the junction.
