Processing, characterization, and potential applications of YBa/sub 2/Cu/sub 3/O/sub 7//Au and YBa/sub 2/Cu/sub 3/O/sub 7//Au/Si superconducting thin films fabricated by rapid isothermal processing assisted metalorganic chemical vapor deposition

摘要

Rapid-isothermal processing (RIP)-assisted metalorganic chemical vapor deposition (MOCVD) has been used for the deposition of high-quality films of YBa/sub 2/Cu/sub 3/O/sub 7/ (YBCO) on insulating substrates at temperatures as low as 610 degrees C. The results of processing and characterization of YBCO films deposited on bulk gold foils and Au/Si substrates by RIP-assisted MOCVD are reported. By the use of YBCO/Au foils, improvement in the performance of Au/YBCO-Si Schottky diodes operating at 50 K is achieved.
