The objective of the Proposed Program is to develop the application of the Edge-defined, Film-fed Growth Process (EFG) to Production of rare earth, gallium oxide compounds in single crystal sheet form for use as a substrate for thin film, epitaxial devices of the superconducting material, YBa2cu3o. Work will be directed to establishing the conditions required to grow good quality single crystal ribbons of the rare earth gallates, NdGaO3 and PrGaO3. Growth of small diameter fibers and thin, flexible tapes of these materials will also be investigated. The latter shaped crystals are intended as a basis for the study of formation of superconducting "wires". This work will provide the foundation from which a scaled-up process may be expected to produce economical, high-quality, large area substrates of these materials. The substrates produced by this method will find extensive application in the fabrication of superconducting and hybrid superconducting-semiconducting electronic devices.
