Outline of Final Research Achievements

Reduced tungsten bronze-type oxide Ba2NaNb5O15 (BNN) oriented ceramics was prepared to investigate thermoelectric (TE) properties. In order to discuss enlarged effective mass, mobility, scattering parameter (r), and carrier density of BNN were estimated by using transport and Hall measurements. In TE properties, BNN showed high absolute Seebeck coefficient (|S|) up to 250 μV/K and electrical conductivity (σ) of 17.1 S/cm, and power factor above 0.12 mW/mK2. Dimension less figure of merit (ZT) and thermal conductivity (k) were evaluated to be 0.1 and 0.5 W/mK, respectively, by using Harman method from room temperature to 200℃.
