摘要：
The microstructure of Bi2(Sr,Ca)3Cu2Ox/Bi2Sr2CuOy/Bi2(Sr,Ca)3Cu2Ox (2212/2201/2212) trilayer films was studied by cross-sectional high-resolution transmission electron microscopy. The trilayer films were fabricated in situ by ion beam sputtering on polished (001) MgO substrates with a thin 2201 buffer layer. The buffer layers significantly improved the surface flatness of the trilayer films. The trilayer films had an epitaxial relationship and the c-axis preferred orientation normal to the substrate surface. The intermediate 2201 layer had a uniform thickness, and the 2212/2201 interfaces were extremely sharp. The results indicated that the epitaxial 2212/2201/2212 trilayer films were suitable for the fabrication of sandwich-type Josephson junctions.
