ZT of the barium cobalt oxide film

Caption

(Left) ZT of all four cobalt oxide films increases with increasing temperature. The barium cobalt oxide film (red diamonds) has the highest ZT among the four, reaching a high ZT value of ~0.55 at 600 °C. (Right) The ZT of the barium cobalt oxide film at 600 °C is comparable to that of commercially available thermoelectric converters (lead-tellurium, PbTe, and silicon germanium, SiGe; Xi Zhang, Yuqiao Zhang, et al. ACS Applied Materials & Interfaces. July 12, 2022).
