The correlated oxide Ca₃Co₄O₉ and Bi₂Sr₂Co₂O_y have a metallic resistivity and a high Seebeck coefficient at room temperature, and their low-layered samples are known as a transparent conducting oxide. It has also been shown that Bi-doped Ca_3-xBi_xCo₄O₉ decreases electrical resistivity while maintaining high Seebeck coefficient. In this presentation, we measured the sheet resistance of low-layered Ca_3-xBi_xCo₄O₉ and Bi₂Sr₂Co₂O_y and we will discuss the performance as a transparent conducting oxide.
