To study the thermoelectric properties of SrTiO 3 doped with lanthanum and dysprosium,the total doping amount was fixed at 20% mol with different amounts of lanthanum and dysprosium contents.As the dysprosium content increased,both the electrical conductivity and thermal conductivity decreased; in contrast,the absolute value of the Seebeck coefficient increased.The power factor reached 1318 μW/K 2 m at 570 K.The lowest thermal conductivity was 2.3 W/mK.The maximum figure of merit (ZT) of 0.36 at 1076 K was obtained for SrTiO 3 doped with 12% dysprosium and 8% lanthanum.
