摘要：
Thermoelectric properties at high temperature of NiO doped with Li and Ti were investigated. Compared to Li-doped NiO (LNO), Ti-doped LNO (LTNO) showed low conductivity and high Seebeck coefficient; however, the power factor of the LTNO increased to as high as 1 x 10(-4) W/mK(2) at 1070K. Ti dopant has a remarkable effect on transport properties of the LNO ceramics. A possible mechanism was discussed.
