Abstract: In the presence of hybridization of the f states with the conduction electrons Ce-based compounds can show large peaks in the temperature dependence of the Seebeck coefficient, which makes them interesting materials for applications.The Seebeck coefficient and electrical resistivity of the bulk, arc-melted, single phase samples of Ce(Ni1xCuxq2Si2 and CeNi2(Si1yGeyq2 alloys were measured over the temperature range of 2 K to 300 K.All the samples exhibited a positive Seebeck coefficient, which reaches up to 50µV/K at 150 K and it can be shifted up to 300 K by appropriate doping.The thermoelectric power factor, P F S 2 /ρ, reached a maximum of 1.4 10 3 Wm 1 K 2 at 290 K and 1.1 10 3 Wm 1 K 2 at 110 K for x 0.25 and y 0.75, respectively.For selected representatives of the studied series thermoelectric properties have been measured up to 1000 K.
