Join us at the International Thermal Conductivity Conference (ITCC) and the International Thermal Expansion Symposium (ITES).
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 ...
A series of compacted Bi0.5Sb1.5Te3 nanoplatelets are synthesized using hydrothermal methods, followed by cold pressing and sintering at temperatures between 300°C and 380°C. A variety of thermal, mechanical and electrical analyses are then performed on the synthesized nanoplatelets including: TPS technique for thermal conductivity, SEM/TEM/AFM to elucidate the mechanical and physical properties of the nanoplatelets, and the Oxford closed cycle cooler cryostat for measurement of electrical ...
