Bi2-xSbxTe3 thermoelectric materials, where x = 1.52 and 1.55 were prepared and evaluated for their thermoelectric properties. Three samples in total were prepared, two with x = 1.52 and 1.55 were synthesized at 140oC and one with x = 1.55 was synthesized at 160 oC. It was determined that the two samples synthesized ...
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 ...
The partial replacement of Ca2+ ions with Eu3+ in the Ca3Co3.95Ga0.05O9+delta system to give polycrystalline samples of Ca3-xEuxCo4O9+delta (x = 0.00, 0.05, and 0.10) was performed in order to assess the effect that the dopant had on thermoelectric properties of this system. ...
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 and increased thermal conductivity. The change in these properties was attributed to electronic effects....
The thermoelectric and magnetic properties of the Ca3Co4-xCuxO9+delta system where x = 0, 0.05, 0.07, 0.10, and 0.15 were investigated as materials of this type have potential for use in thermoelectric generators. The goal of this work was to identify the sample in this system having the highest ...
