Thermoelectric properties of Ce_0.09Fe_0.67Co_3.33Sb₁₂/FeSb_2.1Te multi-layered structures with period of 5 nm were studied in temperature ranging from 300 K to 500 K. Structures were prepared by Pulsed Laser Deposition (PLD) on fused sili- ca quartz glass substrates at the substrate temperature during the deposition Ts = 230°C and Ts = 250°C with the laser beam energy density Ds = 3 Jcm^-2. In the contribution temperature dependencies of the in-plane electrical conductivity, the Seebeck coefficient and the resultant power factor together with room temperature value of thermoelectric figure of merit are presented.
