Abstract
A room temperature superconductor having a metal thin film with negative susceptibility coated upon a substrate. The thin film is covered by a protective coating which prevents it from oxidizing. In one embodiment of the invention multiple layers of chromium with negative susceptibility value separated by a protective coating are mounted upon the substrate to provide a sandwich like structure having increased current carrying capacity.
Claims26
A superconducting device that includes a substrate, a thin metallic film that has a negative susceptibility at room temperature that is mounted upon the substrate, and means to prevent the thin film from oxidizing wherein said thin metallic film is former of chromium.
A superconductor device that includes a substrate, a plurality of multiple layered units mounted one over the other on the substrate, each unit including a thin chromium film having a negative susceptibility and an outer coating of a material that prevents the chromium from oxidizing.
A superconducting device that includes a semi-conductor having p-type and n-type sections, at least one electrical terminal in contact with one of the sections that includes an insulating layer mounted upon the surface of the semi-conductor, a thin chromium film having negative susceptibility mounted upon the insulating layer, and a protective coating placed over the thin film for preventing the thin film from corroding.
The device of claim 34 wherein the protective coating is formed of palladium.
The device of claim 34 wherein the protective coating is formed of an insulating material.
