Thermoelectric properties of layered calcium cobaltite doped by particles of cobalt, copper, and their oxides

Abstract

Our results demonstrate that using inexpensive additives and varying thermal prehistory of ceramics based on the layered calcium cobaltite one can essentially improve its thermoelectric performance. That may be used for development of new high-temperature oxide thermoelectrics based on Ca[3]Co[4]O[9+delta] which will be prospective for effective conversion of high-temperature heat into electrical energy.
