Continuous YBCO deposition onto moved tapes in liquid single source MOCVD systems

In a small scale MOCVD system YBCO films with j(c)(77 K) > 1 MA were deposi ted onto substrates, which were continuously moved through the deposition c hamber. Two routes for the buffer layer deposition onto textured Ni tapes w ere chosen: a) CeO2, LaMnO3 and LaCrO3 films were deposited in hydrogen atm osphere by MOCVD. On LaAlO3 and R-Al2O3 crystals epitaxial films were obtai ned b) textured NiO layers were grown by oxidation of textured Ni tapes. Ba sed on the small scale system an enlarged MOCVD reactor was constructed.
