Researchers are currently developing ways to produce thermoelectric materials, such as skutterudites, with low lattice thermal conductivity. In this paper, a hydrothermal synthesis procedure was developed to fabricate CoSb3 compounds. A thermal constant analyzer measured the thermal conductivity of three CoSb3 samples using the transient plane source (TPS) method. Results showed that thermal conductivity increased with decreasing temperature, and was much lower for the hydrothermal-synthesized CoSb3 samples than other fabrication ...
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 ...
