Investigation of Noble Metal Substrates and Buffer Layers for BiSrCaCuO Thin Films

Matthiesen, M. M. / Rubin, L. M. / Williams, K. E. / Rudman, D. A.

Abstract Noble metal buffer layers and substrates for Bi2Sr2CaCu2O8(BSCCO) films were investigated using bulk ceramic processing and thin film techniques. Highly oriented, superconducting BSCCO films were fabricated on polycrystalline Ag substrates and on Ag/MgO and Ag/YSZ structures. Such films could not be produced on Au or Pt substrates under any annealing conditions. In addition, superconducting BSCCO films could not be produced on Ag/Al2O3, Ag/SiO2/Si, or Ag/(Haynes 230 alloy) structures using high annealing temperatures (870°C). However, oriented, although poorly connected, superconducting BSCCO films were fabricated on Ag/Al2O3 structures by using lower annealing temperatures (820°C). Once lower processing temperatures are optimized, Ag may be usable as a buffer layer for BSCCO films.
