The effects of Si doping on the thermoelectric and magnetic properties of Ca0.98Bi0.02Mn1−xSixO3−delta with x = 0.00, 0.02 and 0.03
Single phase, orthohombic structured Ca0.98Bi0.02Mn1−xSixO3−delta (x = 0.00, 0.02 and 0.03) samples were prepared using solid state reaction. The authors investigated whether they could improve the thermoelectric properties of the ...Read More
Correlation Between the Electronic Structure and the Thermoelectric Properties of Gd-Doped CaMnO3−delta
The effects of the substitution of Ca with Gd in the Ca1-xGdxMnO3-delta system were investigated. It was determined that the partial substitution of Gd resulted in decreased resistivity ...

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 ...Read More
Samples of Ca0.98RE0.02MnO3- delta (RE = Sm, Gd, and Dy) were tested for their thermoelectric and magnetic properties. It was determined that 2% doping at the Ca site with ...Read More
Thermoelectric properties of n-type Ca(1-x)Bi(x)Mn(1-y)Si(y)O(3-delta) (x = y = 0.00, 0.02, 0.03, 0.04, and 0.05) system
CaMnO3 has been proposed for use in thermoelectric materials, due to its favourable thermoelectric properties. In this article, the effect of doping using bismuth and silicon to replace calcium and ...
