Thermoelectric materials are currently being researched as a source of energy in order to reduce carbon dioxide emissions. The efficiency of these materials depends on their Seebeck coefficient, electrical resistivity, and thermal conductivity, as well as the absolute temperature. Cobalt oxides (Ca3Co4O9+delta) have been researched extensively as potential thermoelectric materials because of their high Seebeck coefficient and low electrical resistivity and thermal conductivity. Systems have been studied ...
