3 p-type cuboid was created using hydrothermal synthesis, cold pressing, and evacuated-and-encapsulated sintering in a Pyrex ampoule. The figure of merit (z) was determined by finding three transport parameters: electrical conductivity, thermopower, and thermal conductivity. The thermal conductivity measurements on the three (A, ...

3. 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-Cu
2−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-Cu
2−xSe at room temperature is found to be larger than that ...

Nanostructured SnSe was created using hydrothermal methods and sintering in an evacuated-and-encapsulated ampoule. The effects of the synthesis and thermoelectric properties of SnSe using hydrothermal synthesis at low temperatures followed by evacuating-and-encapsulating sintering were then further investigated to determine their viability. One of the investigations centered around determining the thermal conductivities of the samples. The anisotropy of the thermal conductivity of the pressed polycrystalline SnSe was measured using the transient ...

A series of polycrystalline Sn1-xNaxSe with x = 0.00, 0.02, 0.04, 0.10 were fabricated using hydrothermal synthesis, followed by evacuated-and-encapsulated sintering. Their thermoelectric properties were then evaluated. The thermal constant analyser was used to find the thermal conductivity of each system by using the transient plane source (TPS) technique. The thermal conductivity was then used in determining the thermoelectric figure-of-merit, the ZT value of the system....
