Thin films of the high-temperature superconductor YBa2Cu3Oy have been deposited on Al2O3 and MgO substrates by dc magnetron sputtering. Raman-scattering experiments have been carried out on these films at various temperatures. The results of these experiments have been used to estimate the amount of impurity phases in the films, to characterize the actual superconducting films, and to test for any preferential orientation within the film. Vibrational modes of the superconductor were found at 148, 226, and 338 cm−1 in both sets of films, at 446 and 491 cm−1 in the Al2O3 films, and at 441 and 500 cm−1 in the MgO films. The measured frequencies of the highest energy modes have been used to determine the oxygen content of the films.

The thin films of SiO and SiON were deposited individually by the inclination opposite target type DC magnetron sputtering equipment onto the glass substrate. And it was deposited IZO(In2O3 (90wt.%) + ZnO(10wt.%)) on those films. The effects of SiO and SiON were investigated on properties of IZO thin films. AFM images of IZO thin film included SiON film were shown smoother surfaces than that included SiO film. Multi layers of IZO were shown good properties because it have high transmissivity. Resistivity is in inverse proportion to Mobility. If it deposited SiO and SiON, generate layer of change between two layers(SiO or SiON + Substrate). Layer of change influenced resistance because Oxygen content was more than single layer of IZO. In case of using PET substrate, it influenced stronger than Glass substrate for rigid gas permeable and osmosis.

Current Steps

Bi 1.75 Pb 0.17 Sr 2 Ca 2.1 Cu 3.2 O y thin films with zero resistivity at 115 K, were prepared by dc magnetron sputtering and subsequent high-temperature annealing. Josephson bridges were fabricated by crossed contact of two cleaved planes of the thin films. Self-induced current steps and multi photon-assisted tunneling currents due to quasi-particles tunneling across the oxide gap barriers were observed. It was proved that the formation of the oxide gap barriers was due to oxidation of the Cu component and the extrication of Ca near the crossed contact of the thin film by soaking the thin film in liquid nitrogen. It seems possible to fabricate smaller bridge with a single junction by the use of thinner as-grown films with smoother surfaces.

Post Annealing

Superconducting YBCO thin films have been fabricated by dc magnetron sputtering from a pair of stoichiometric YBCO superconducting targets on polycrystalline ZrO 2 substrates. The post-annealing superconducting films exhibit the properties with the critical onset temperature of 95 K and zero resistivity temperature at 83 K. The relation between the composition of the film and the radial position of the substrate is investigated. The XRD analysis proved that the films are mainly orthorhombic polycrystalline structure.
