Biaxially textured single buffer layer for superconductive articles

摘要

A thick atomically ordered single buffer layer for use in the integration of high temperature superconductor films with metallic substrates is disclosed. The buffer layer is a doped cerium oxide (CeO2) material, where the doping reduces layer cracking through the modification of thermal expansion coefficient and film strain properties, while adjusting chemical properties and lattice parameters to better match those of the substrate and HTS layer.
