Pd-doped TiCo1-xPdxSb (0 £ x £ 0.08) half-Heusler compounds were synthesized by a solid-state reaction method and their electrical transport properties in the temperature range of 300-900 K were investigated. Single phase TiCo1-xPdxSb was obtained in the range of 0 £ x £ 0.08. The lattice parameters increased with Pd content. Doping of Pd on the Co site resulted in a great increase of electrical conductivity without significant decrease of Seebeck coefficient. A large power factor of 26 µW/K2 cm was observed for TiCo0.92Pd0.08Sb compound at 300 K.
