Abstract
A superconductor structure having a substrate, the substrate defining a surface. Applied to the surface of the substrate is a barrier layer. Applied to the barrier layer is a layer of superconductive material comprising copper and oxygen. The barrier layer serves to prevent the interaction of the superconductive material with the substrate, thus destroying the stoichiometry of the superconductive material and resulting in a loss or decrease in superconductivity. A protective layer is, optionally, applied to the layer of superconductive material.
