Technology of superconducting thin films on Si, SiO sub(2), and Si sub(3)N sub(4) for vacuum microelectronics

A study of YBaCuO films on Si, SiO sub(2), and Si sub(3)N sub(4) substrates demonstrates that rapid thermal processing can suppress the film-substrate reaction during the post-growth oxygen annealing. With the onset of superconductivity above 95 K, YBaCuO films annealed for 6 s at 940 degree C show...

Zusammenfassung:A study of YBaCuO films on Si, SiO sub(2), and Si sub(3)N sub(4) substrates demonstrates that rapid thermal processing can suppress the film-substrate reaction during the post-growth oxygen annealing. With the onset of superconductivity above 95 K, YBaCuO films annealed for 6 s at 940 degree C show T sub(c)(0) above 70 K for the SiO sub(2)-Si substrate. These results as well as results of others suggest that high T sub(c) oxide superconductors could be used as electron sources or as cold emitters, gates, and collectors.
