摘要：

Highly c-axis oriented YBa2Cu3O7-x superconducting thin films have been, in situ, deposited directly on sapphire substrate by a remote microwave plasma-enhanced metalorganic chemical vapor deposition process (PE-MOCVD). The films were deposited at a substrate temperature of 730°C followed by a fast cooling. The as-deposited films show attainment of zero resistance at 82 K and have critical current density of 104 A/cm2 at 70 K. ac susceptibility measurement indicated that the films contain a single superconducting phase. PE-MOCVD was carried out in a commercial-scale MOCVD reactor with capability of uniform deposition over 100 cm2 per growth run.
