YBCO coated conductors fabricated by a MOCVD (metal organic chemical vapor deposition) method
MOCVD (metal organic chemical vapor deposition)법으로 제조한 YBCO 초전도 coated conductors
Abstract
MOCVD method is one of promising techniques which can fabricate YBCO coated conductors in a low Price A continuous reel-to-reel MOCVD device using a dispersed solid source was designed and manufactured. YBCO films were deposited on various substrates of metallic silver, (100) MgO and SrTiO3 single crystals. The chemical composition of the metal organic sources was changed to optimize the processing condition associate to the deposition of the stoichiometric Y3a2Cu3O7-y. We report the superconducting transition temperature, surface morphology and chemical composition of the YBCO film surfaces.
