Abstract : As described in our proposal for making YBCO/SrTiNbO/YBCO junctions, the success of this project relies on work in three different thrusts: Growth of high quality, ultra-thin high-quality YBCO films. Acquisition of metallically doped SrTiO3 substrates with high structural quality. The fabrication and characterization of S-N-S Josephson structure based on YBCO/SrTiNbO heteroepitaxy. While there has been encouraging progress in the thin film growth part, problems were found in obtaining metallically doped SrTiO3 substrates with the desired electrical/structural properties. A better alternative for the doped SrTiO3 will be the growth of YBCO films on top of a metallic oxide thin film SrRuO3, as will be described in more detail in this report. jg p.2
