Exploring the High-Temperature Electrical Performance of Ca<sub>3−x</sub>La<sub>x</sub>Co<sub>4</sub>O<sub>9</sub> Thermoelectric Ceramics for Moderate and Low Substitution Levels

Aliovalent substitutions in Ca<sub>3</sub>Co<sub>4</sub>O<sub>9</sub> often result in complex effects on the electrical properties and the solubility, and impact of the substituting cation also depends largely on the preparation and processing method. It is also w...
