Book excerpt: High quality YBa2Cu3O7-x films were grown in-situ on LaA103 (100) by a novel single liquid source plasma-enhanced metalorganic chemical vapor deposition process. The metalorganic complexes M(thd)n, (thd = 2,2,6,6- tetramethyl-3,5-heptanedionate; M = Y, Ba, Cu) were dissolved in an organic solution and injected into a vaporizer immediately upstream of the reactor inlet. The single liquid source technique dramatically simplifies current CVD processing and can significantly improve the process reproducibility. X-ray diffraction measurements indicated that single phase, highly c-axis oriented YBa2Cu3O7-x was formed in-situ at a substrate temperature 680 deg C. The as-deposited films exhibited a mirror-like surface, had transition temperature Tco = 89 K, Delta Tc
