Abstract

Materials issues relevant to the growth of high quality YBa2Gi3017-x/SrTiO3 (YBCO/STO) bilayers for use in superconducting field effect devices have been studied. Different substrate materials and growth conditions were investigated. NdGaOa was determined to be the most promising substrate material due to its low surface roughness and good lattice match to YBCO. The electrical properties of ultrathin YBCO and YBCO/STO bilayers grown by Pulsed Laser Deposition were also investigated as a function of substrate temperature. The optimized deposition temperature for lOnm thick YBCO was found to be 60C below that of thick (lOOnm) films. STO overlayers with dielectric constant, e - 700 and breakdown field, EgD “625kV/cm were fabricated. The STO/YBCO interface was also studied.
