摘要
Abstract
Li doped NiO samples were prepared by sol-gel method. The effects of Li doping on the thermal electric properties of NiO were investigated in detail. The results show that no impurity phase exists in the substitution of Li at Ni site. The electrical conductivity and Seebeck coefficient of Ni1-xLixO samples were measured from 300 to 750K. The electrical conductivity increases dramatically with Li content. However, the Seebeck coefficient decreases with Licontent. The power factor of Ni0.94Li006Oreaches 1.9X10 5W-m 1.K 2 at 750K, which portends that the higher value of power factor would be obtained at higher measuring temperature.关键词
