Реферат
Cobalt base metal oxide ceramics are s new promising thermoelectric materials. In this work, polycrystalline samples of the Er1-xAxCoO3-δ and Ho1-xAxCoO3 (A = Ca, Sr; 0,05 ≤ х ≤ 0,95) compositions have been for the first time synthesized using the standard solid-phase method. The effects of impurities on the transport and thermoelectric properties have been studied for these samples. The substitution of 5 % Ho3+ (or Er3+) for Sr2+ is found to change the sign of the Seebeck coefficient at 300 K. This demonstrates that not only holes but also electrons can be charge carriers in studied samples.
Ключевые слова Thermoelectric material, ceramic cobaltites, Seebeck coefficient, thermoelectric power, electrical resistivity, Perovskite cobalt metal oxides.
