Hydrothermal methods were used to synthesize nanoplatelets of Bi2-xSbxTe3. In this article, the electrical conductivity, thermopower, and thermal conductivity were the temperature-dependent transport parameters that were determined to calculate the dimensionless figure of merit, ZT. The thermal conductivity measurements were carried out using the transient plane source (TPS) technique with the thermal constants analyzer. The alloy had a low thermal ...
Materials of β-Cu2−xSe were fabricated by using hydrothermal synthesis followed by evacuating-and-encapsulating sintering. These materials were then characterized using powder X-ray diffraction, field-emission scanning electron micrograph, electronic and thermal transport. Thermal conductivity measurements were carried out utilizing transient plane source (TPS) techniques using a thermal constants analyzer. The thermal conductivity of β-Cu2−xSe at room temperature is found to be larger than that ...
This article investigates the effect of aluminum doping on the thermal conductivity and other thermoelectric properties of nanostructured Zn1•XAlXTe (0 ≤ X ≤ 0.15) for a temperature range of 300 K – 600 K. The thermal conductivity was measured using the transient plane source (TPS) technique by a thermal constants analyzer. It was found that with increasing doping of aluminum, the thermal conductivity decreased, and with increasing temperature thermal conductivity also decreased. The decreasing of thermal ...
