Abstract
The electrical conductivity and thermoelectric power for solid solutions of La(2)Cu(0.9)M(0.1)O(4) (M = Mn, Fe, Co and Ni) prepared by polymeric precursor synthesis were measured between 300 and 1173 K to test its suitability as a thermoelectric material. Fe-, Mn-and Ni-doped compositions exhibited a metal-semiconductor transition with decreasing temperature, whereas Co doping showed a semiconducting behaviour in the entire temperature range of measurement. With Cu-sites doping in La2CuO4, power factors were not enhanced
