Abstract

We tried to deposit (Sr1−xCax)0.9CuO2-δ films, so-called “the infinite-layer” structure, of (100) SrTiO3 substrates by using radio-frequency thermal plasma evaporation. The crysta structure of these films was confirmed by X-ray diffraction to consist of the (00l) oriented infinite-layer structure. However, the temperature dependence of resistivity showed no superconductivity in spite of varying ratios of Sr/Ca. A description is given of attempts to induce superconductivity in the infinite-layer films by the introduction of holes, namely by O2 plasma annealing and Na-doping.
