Abstract. The solution deposition of YBa2Cu3O7-δ (Y123) high temperature superconducting thin films was studied. The films were prepared from a polymer-containing precursor onto SrTiO3 (001) and LaAlO3 (001) substrates and mineralized at high temperatures. The process depended on details of the film preparation in a delicate fashion, resulting either in superconducting or non-superconducting thin films. To elucidate this difference in conductivity, scanning electron microscopy and several X-ray diffraction techniques were used to characterize the resulting Y123 layers. Both the morphology of the film and the percentage of non-superconducting minority components are likely to be the origin of the difference in the conductance behavior at low temperatures.
