Abstract

Previous work has demonstrated the ability to grow extremely high quality Tl_{0. 5}Pb_{0. 5}Sr_{1. 6}Ba_{0. 4}Ca₂Cu₃O_x epitaxial films up to 15 μ m thick using melt growth techniques on single crystal LaAlO₃ substrates. This melt growth process is an ideal candidate for producing high quality superconducting films on flexible metal substrates with textured buffer layers; however, the textured buffer layer of choice, cubic yttria-stabilixed zirconia (YSZ), appears to be incompatible with the melt growth of Tl-Pb-Sr-Ba-Ca-Cu-O films. In this work, we investigate textured buffer layers which are compatible with the epitaxial growth of Tl_{0. 5}Pb_{0. 5}Sr_{1. 6}Ba_{0. 4}Ca₂Cu₃O_x films. Crucial properties for the successful development of a suitable buffer layer are lattice matching, chemical stability, and texture. Buffer layer materials investigated are CeO₂ and LaAlO₃ grown using a UV (248 nm) pulsed excimer laser deposition system equipped with multiple targets and a controlled ambient. Influence of substrate temperature and ambient gas pressure and flow on buffer growth are analyzed via XRD characterization. Highly textured buffer layers have been fabricated.
