Low-temperature thermoelectric characteristics of Ca32xYbxCo3.95Ga0.05O9+d (0 < x < 0.10)

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 ...

Thermoelectric Properties of Ca1−xGdxMnO3−delta (0.00, 0.02, and 0.05) Systems

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+ ...

Thermoelectric properties of Ca3-xEuxCo3.95Ga0.05O9+delta (0 < x < 0.10)

The partial replacement of Ca2+ ions with Eu3+ in the Ca3Co3.95Ga0.05O9+delta system to give polycrystalline samples of Ca3-xEuxCo3.95Ga0.05O9+delta (x = 0.00, 0.02, and 0.10) was performed in order to assess the effect that the dopant had on thermoelectric properties of this ...

Electronic transport of co-doped misfit-layered cobaltites

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 ...
