Abstract

Indium-tin oxide (ITO) thin films were examined as a buffer layer between high-Tc superconducting Y-Ba-Cu-O thin films and glass substrates. It was found that ITO film can become a diffusion barrier between the superconducting film and glass substrate, and that it does not cause any cracks in Y-Ba-Cu-O film if an appropriate silicate glass substrate is chosen. The superconducting film deposited on ITO/Glass below 700°C has shown onset transition temperatures up to 91 K and zero resistivity temperatures at 50 K.
