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 Ca3-xYbxCo3.95Ga0.05O9+delta where x = 0.00, 0.02, 0.05, and 0.10 were determined at temperatures less than 300 K. It was determined that the partial substitution of Yb3+ for Ca2+ resulted in an increase in resistivity and thermopower. The thermal conductivity was found to ...
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 ...
The thermoelectric properties of the Ca1-xGdxMnO3-delta system where x= 0.00, 0.02, and 0.05 were evaluated. It was determined that the sample with the lowest electrical resistivity was the Ca0.95Gd0.05MnO3-delta sample. This result was attributed to the increase content of Mn3+ in the Mn4+ ...
