Redox-Promoted Tailoring of the High-Temperature Electrical Performance in Ca<sub>3</sub>Co<sub>4</sub>O<sub>9</sub> Thermoelectric Materials by Metallic Cobalt Addition

Redox-Promoted Tailoring of the High-Temperature Electrical Performance in Ca<sub>3</sub>Co<sub>4</sub>O<sub>9</sub> Thermoelectric Materials by Metallic Cobalt Addition

This paper reports a novel composite-based processing route for improving the electrical performance of Ca<sub>3</sub>Co<sub>4</sub>O<sub>9</sub> thermoelectric (TE) ceramics. The approach involves the addition of metallic Co, acting as a pore filler on oxidation,...
