C-axis textured single phase superconducting YBa/sub 2/Cu/sub 3/O/sub 7-x/ films have been successfully grown on the yttria-stabilized zirconia (100) substrates by using the metalorganic chemical vapor deposition technique. After the post annealing the films deposited on the yttria-stabilized zirconia substrates exhibited a highly textured x-ray pattern with c-axis perpendicular to the substrate surface. These films show an onset superconducting transition temperature of 93K with the resistance becoming zero at 84K. The films deposited on sapphire show a semiconducting feature in the normal state with a broad superconducting transition at much lower temperatures (10-40K). In order to gain some insight onto the growth process, we also studied the mass transport of metalorganic compounds as a function of source temperature, flow rate and reactor pressure. 15 refs., 10 figs.
