摘要：

We have investigated the incorporation of carbon into infinite-layer BaCuO2 films using a sputtering method. When carbon was doped, the films showed a modulated structure with 2c and 3c periodicity along the c-axis of the BaCuO2, indicating that the carbon-incorporated layers are ordered. Transmission-electron-microscopy observation suggested that the ''2c'' and the ''3c'' structures were isomorphous with the 1201 (endmember) and 1212 phases of homologous (C,Cu)Ba2Can-1CunOx, respectively. The ''2c'' modulated film exhibited a superconducting transition around 40-50 K.
