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 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 'graphene-like' mechanical exfoliation of Bi2Te3 films is shown to have a significant effect on the thermoelectric properties of these films. The modification of thermal conductivity due to exfoliation leads to enhanced thermoelectric properties, known as figures of merit (ZT).Two different experimental techniques were used in order to determine the thermal conductivity of the exfoliated films: transient plane source (TPS) and laser flash technique (LFT). Annealing was performed ...
