Superconducting Thin Films Composites and Junctions
Abstract
Four methods for growing thin films of high Tc superconductors have been developed and properties of the films have been investigated. A new superconducting structure of composition Y2Ba4Cu8O20- has been discovered. In a number of ways it has properties which are better than those of the YBa2Cu3O7 structures. It is less anisotrophic in the CuO2 (conducting planes) and therefore has less (or no) twinning. It retains oxygen under vacuum conditions and thus may be superior for making planar Josephson Junctions. Keywords: Yttrium compounds, Barium, Copper compounds, Oxides, Epitaxial growth, Vapor deposition.
