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 ...
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 thermoelectric properties of the co-doped misfit-layered cobaltites of Ca3-xAgxCo3.95Fe0.05O9+delta (x=0.0, 0.1, 0.2, 0.3) were investigated at temperatures between 300 and 700 K. It was found that the thermopower increased with increasing temperature. The thermal conductivity was found to increase with increasing Ag+ content in ...
Two series of co-doped mifit-layered cobaltites were prepared with compositions of Ca3-xYbxCo4-yAgyO9+delta and Ca3-xEuxCo4-yAgyO9+delta. All of the samples exhibited an increasing thermopower as temperature was increased up to a temperature of 700 K. The sample with the highest power factor ...
A new application for the transient hot-wire technique for thermal conductivity measurements has been described. It is intended to provide an accurate means of implementation of the method to the determination of the thermal conductivity of solids exemplified by a standard reference ceramic material. Measurements ...
