Abstract

Thin films of Y-Ba-Cu-O have been deposited on barrier layers of SrTiO3 and ZrO2 by laser ablation or RF planar magnetron sputter deposition. The barrier layers are required to prevent interactions of the deposited superconducator with the underlying semiconductor and at the same time enhance the texture in the superconductor to increase the critical current density. The ability of various processing steps to enhance these properties and simultaneously allow scale-up to coat larger areas successfully are discussed.
