Properties of thermoelectric Ce sub(0.09)Fe sub(0.67)Co sub(3.33)Sb sub(12)/FeSb sub(2)Te multi-layered structures prepared by laser ablation

Multi-layered Ce sub(0.09)Fe sub(0.67)Co sub(3.33)Sb sub(12)/FeSb sub(2.1)Te structures composed of thin equidistant layers were prepared by Pulsed Laser Deposition on fused silica quartz glass substrates. The structures were prepared at different substrate temperatures (230 [degrees]C or 250 [degrees]C) applying the laser beam energy density of 3 Jcm super(-2). In the contribution we present some thermoelectric properties such as the in-plane electrical conductivity, the Seebeck coefficient and the power factor for the multi-layered structures in the temperature range from 300 K to 500 K. Comparison of multi-layered structure's thermoelectric properties with single thin Ce sub(0.09)Fe sub(0.67)Co sub(3.33)Sb sub(12) and FeSb sub(2.1)Te layers is given. A cross sectional picture of the multi-layered structure made by Scanning Electron Microscope is presented for the thicker multi-layered structure.
