Buffer layer structure based on doped ceria for providing optimized lattice match with a YBCO layer in a conductor

摘要

A buffer layer structure based on doped ceria for providing optimized lattice match with a YBCO layer in a conductor, a lattice matching layer for use in said structure and process of manufacturing thereof. Said buffer layer comprises a CeO2 layer doped with a dopant, and has a superconductive layer of YBCO on said CeO2 layer. The invention is characterized in that the CeO2 layer is a lattice matching layer.
