Methods for high tc superconductor film deposition

Abstract From the Canadian patent

Tc SUPERCONDUCTOR FILM DEPOSITION ABSTRACT OF THE DISCLOSURE, The present invention describes two simple methods to prepare high Tc multi element superconductor films. In the first method, metallic elements (or oxides) are deposited sequentially on substrates in a vacuum system. The film composition is controlled by controlling the amounts of the source materials introduced into the boats. In addition one or more of the, elements (or oxides) are introduced to the films by treating the films in an environment containing such elements. The other method described involves the deposition of films on substrates with arbitrary shape using a non vacuum paint on method.
