High-Temperature Thermoelectric Properties of Pb-and La-Substituted Bi2Sr2Co2Oy Misfit Compounds

摘要：

　　Pb-and La-substituted (Bi,Pb)2(Sr,La)2Co2Oy samples were prepared by solid-state reaction method and the effect of element substitution on the high-temperature thermoelectric properties was investigated.It was found that the presence of Pb and La elements improved the thermoelectric properties of the Bi2Sr2Co2Oy system owing to the simultaneous increase of conductivity and Seebeck coefficients.The optimal thermoelectric performance was obtained in Pb and La co-substituted samples and the power factor could reach 2.1 × 10-4Wm-1K-2 at 1000K.
