Thin films of Y-Ba-Cu-O on silicon and silicon dioxide

Abstract

Thin films of the high-temperature superconductor Y-Ba-Cu-O near the 1:2:3 stoichiometry were deposited on single-crystal silicon and oxidized silicon with a zirconia buffer layer. Zero-resistance transition temperatures up to 83 K have been measured on the films formed by a process of sequential evaporation and furnace annealing.
