This patent describes a superconducting structure. It comprises a sapphire substrate having a thickness of at least 0.1 multimeters; a thin buffer layer of calcium titanate having a thickness of no more than about 3,000 Angstroms deposited on a surface of the substrate; and a thin film of high temperature metal cuprate superconductor having a T{sub c} above about 30K deposited on a surface of the buffer layer.
