摘要：

The microstructure of Sr1-xCuO2-delta thin films with x=0.00 and 0.10 was investigated by X-ray diffraction and transmission electron microscopy. Both films were single phase of the ''infinite-layer'' structure. However, in both films certain defects were observed, being extended along the ac-plane. The defect was found to be intergrown Sr2CuO3 crystallites between the infinite-layer structure Sr1-xCuO2-delta crystals. It was suspected that one of the reasons why superconductivity was not observed in these films was that Sr-deficient ab-planes were not observed in these film samples.
