摘要：

To clarify the thermoelectric properties of the layered cobalt oxide Ca3Co4O9 epitaxial film fabricated by the topotactic ion-exchange method [K. Sugiura et al., Appl. Phys. Lett. 89, 032111 (2006)], the electrical resistivity (rho), Hall coefficient (R-H), and Seebeck coefficient (S) of high quality Ca3Co4O9 epitaxial film were examined over the temperature range 10-1000 K. The film exhibited a low rho of 4.0 x 10(-3) Omega cm and a large S of similar to+200 mu V K-1, which leads to the thermoelectric power factor of 1.0 x 10(-3) W m(-1) K-2, at 1000 K. Furthermore, the film exhibited good thermal stability at 1000 K in air.
