Abstract
METALORGANIC CHEMICAL VAPOR DEPOSITION (MOCVD) OF METALLIC OXIDES IS AN ESTABLISHED TECHNOLOGY IN THE ELECTRONICS INDUSTRY FOR PRODUCTION OF THIN FILM INSULATORS AND TRANSPARENT CONDUCTORS WITH TAILORED PROPERTIES. APPLIED TOTHE NEW SUPERCONDUCTING CERAMIC MATERIALS SUCH AS YBA2CU30X MOCVD COULD PRODUCE FILMS IN OXYGEN WHICH DO NOT REQUIRE SINTERING, FILMS WHICH MAY GROW EPITAXIALLY ON SINGLE CRYSTAL SUBSTRATES (RESULTING IN VERY HIGH CRITICAL CURRENT DENSITIES COMPARED TO POLYCRYSTALLINE MATERIAL), AND FILMS OF EXCEPTIONALLY HIGH PURITY WITH UNIFORM COMPOSITION AND CRYSTAL PHASES. THE OBJECTIVE OF PHASE I IS TO DEMONSTRATE THAT MOCVD OF YBACUO ON ZIRCONIA, ALUMINA, COATED ALUMINA OR STRONTIUM TITANATE YIELDS A UNIFORM SUPERCONDUCTING FILM WITH A SMOOTH SURFACE. FILMS WILL BE CHARACTERIZED FOR TC,JC, AND STRUCTURE.
