Abstract

We synthesize hexagonal tungsten oxides CsxWO3 (x = 0.12 ∼ 0.33) by the hydrothermal method and investigate their thermoelectric property. The title compounds show the metallic behavior. The Seebeck coefficient increases near the band edge in the small cesium ratio x. The maximal value of the power factor and the dimensionless figure of merit ZT are about 3μW/K2cm and 0.03, respectively.
