Rapid Synthesis of the YBa2Cu3Ox Film on Metal Substrate by Chemical Vapor Deposition Technique

Abstract
A new chemical vapor deposition technique has been developed for rapid (max. 24 µm/h) formation of the oxide superconductor film on a metal substrate. In this system, blended β-diketonate chelates of source materials were slowly fed to the vaporizer with carrier gas. The source gas from the vaporizer and O2 gas were introduced into the reactor. We realized a superconducting YBCO thin film that had a T c=87 K on a Hastelloy C-276 substrate.
