Superconductor articles with epitaxial layers

摘要

A superconductor article (110) is described which comprises a substrate (112), a first epitaxial buffer layer (114) on the substrate and a second layer (116) disposed on the surface of the first layer, the second layer being formed of superconductors and precursors of superconductors, wherein the surface of the first layer has low pore density and/or inclusions with small average particle size diameter.
