Properties of in-Situ Superconducting Y1Ba2Cu3O7-x Films by Molecular Beam Epitaxy with an Activateditu growth was achieved by incorporating reactive oxygen species produced by a remote microwave plasma in a flow-tube reactor. The epitaxial (001) orientation is demonstrated by X-ray diffraction, and ion channeling. In-situ reflection high energy electron diffraction showed that a layer by layer gr

Properties of Y-Ba-Cu-O Thin Films Grown in-Situ at Low Temperatures by Co-Evaporation and Plasma Oxed to obtain high oxygen pressure on the substrate surface, while maintaining a low pressure at the sources and rate monitors. This results in as-deposited films which are superconducting at 73K on silicon, 68K on sapphire, and 84K on strontium titanate substrates. These are the highest transition t

Preparation of Thin Films YBaCu(F)O with High Tc and Jcmaterials, including MgO, ZrO, and SrTiO., were studied. Annealed films deposited on SrTiO. substrates were found to be epitaxial and had the best superconducting properties. Transport measurements on the best films show a sharp resistive transition at a temperature T.(R=0) of 90 K and have critical

As-Deposited Superconducting Y-Ba-Cu-O Thin Films on Si, SiO2, GaAs and Ni/Cu Substrates by High Pre without further annealing treatment. The superconductivity of the films is Tc(onset)=95K and Tc(zero)=70K. The targets were Y-Ba-Cu-O compounds made by solid state reaction. The substrate temperature is lower than 450°C. X-ray analysis indicates that the 0.6~2μm films consist of predomintly the ort

The Bi-based films form in at least two compounds, a lower T. phase with a 2212 composition and T. ≈ 80 K and a higher T. phase with a nominal composition of 2223 and a T. ≈ 105 K. The higher T. phase is very difficult
