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.

Abstract: A process for producing a solid state battery successively comprising, superimposed between two metallic contact elements, a layer or thin film of an alkali metal which provides a source of ions, a layer or thin film of ion-superconducting solid electrolyte glass of high ionic conductivity and a layer or thin film of a layered intercalation compound capable of inserting ions issued from the alkali metal film. The lamellae of the thin film or layer of layered compound are oriented substantially perpendicularly parallel to the surface of the solid electrolyte. The process includes forming the layer or thin film of layered intercalation compound by forming a periodic irregularity in only the surface atoms of a substantially smooth substrate surface, and molecular beam depositing the layer or thin film of layered intercalation compound on the substrate surface containing the periodic irregularity of surface atoms. The periodic irregularity of surface atoms conditions the nucleation starting of the layered growth.

Abstract: This invention relates to a process for producing a solid state battery successively comprising, superposed between two metallic contact elements, a layer or thin film of an alkali metal such as lithium, constituting a source of ions, a layer or thin film of a superionic solid electrolyte and a layer or thin film of a layered intercalation compound capable of inserting ions issued from the alkali metal film. The lamellae of the film of layered compound are oriented so that their c-axis is substantially parallel to the surface of the solid electrolyte. The process consists essentially in making the layer or thin film of layered compound by direct grafting on the film which is to serve as substrate therefor, on which is initially impressed a grating which conditions the nucleation starting the crystal growth by means of the techniques of molecular beam deposition. The invention also relates to a battery made in accordance with this process.
