Abstract
This invention is directed to the metal organic chemical vapor deposition (MOCVD) formation of copper oxide superconductor materials. Various source reagents of Group II elements suitable for high temperature superconductor (HTSC) material formation are described, including beta-diketonates, cyclopentadienyls, alkyls, perfluoroalkyls, alkoxides, perfluoroalkoxides, and Schiff bases, as well as complexes of such Group II compounds, utilizing monodentate or multidentate ligands to provide additional coordination to the Group IIA atom, so that the resulting complex is of enhanced volatility characteristics, and enhanced suitability for MOCVD applications. Also disclosed are methods of synthesizing such compounds and complexes, including a method of making Group II metal beta-diketonate compounds having enhanced thermal stability characteristics.
