Abstract

We report high temperature thermoelectric properties of doped delafossite oxide CuRh0.9Mg0.1O2. The parent compound CuRhO2 is a band insulator and becomes metallic upon Mg doping for Rh. We found that polycrystalline CuRh0.9Mg0.1O 2 shows a large thermoelectric power S ∼ +270 μV/K despite its low resistivity ∼ 6 mΩcm at high temperatures around 1000 K. Combining these with a thermal conductivity κ ∼ 80 mW/cm K, we estimate a large dimensionless figure of merit ZT ∼ 0.15 at 1000 K.
