Abstract: Measurements were carried out to determine the electrical resistivity, thermal conductivity and Seebeck coefficients of a series of Fe-doped misfit-layered oxides (Ca3Co(4-x)Fe(x)O(9+delta) (x=0, 0.05, 0.1, and 0.2)). The thermal conductivity experiments were carried out using a Hot Disk Thermal Constants Analyzer via the TPS technique. XRD was also used to characterize the Fe-doped oxides. Overall, the transport properties of the Fe-doped oxides were studied and it was found that the replacement of Co with Fe leads to better thermoelectric properties.
