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

Author(s): , ,

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...

Thermoelectric properties of n-type Ca1-xBixMnO3-delta (0.00, 0.02, and 0.05) system

Author(s): , ,

Calcium is partially substituted by bismuth in the Ca1-xBixMnO3-delta (x=0.00, 0.02, and 0.05) system in order to determine how this substitution affects the electrical resistivity, thermopower, and thermal conductivity. The ...
