C-axis oriented yba₂cu₃o_6.8 films on amorphous silicate glasses using laser deposition

In situ laser deposition was used to fabricate YBa₂Cu₃O_6.8 (YBCO) films on amorphous glasses. Yttrium stabilized zir- conia (YSZ) and conducting indium-tin-oxide (ITO) were used as the buffer layers to improve the transport properties of YBCO films. There was negligible interdiffusion occurring at the interfaces. YBCO films were strongly c-axis oriented normal to the substrate. However, those films were randomly oriented in the a-b plane. T_c’s of 81 K and 72 K were achieved for YBCO films, with a YSZ buffer and an ITO buffer, respectively. Also, the resistivity of the ITO buffer fabricated by laser deposition was in the order of 10^-4 Ω-cm.
