Improvement on the low-temperature thermoelectric characteristics of Ca3xYbxCo4O9bdelta (0rxr0.10)

The low-temperature thermoelectric properties of Ca3-xYbxCo4O9+delta systems (x = 0, 0.02, 0.05, and 0.10). It was determined that these systems produced positive thermopower, indicating that the dominant carriers were holes. The electrical resistivity and thermopower were found to increase with increasing Yb3+ content, and the thermal conductivity ...

Low-temperature thermoelectric and magnetic properties of Ca3−x Bi x Co4O9+delta (0 < x < 0.30)

Calcium is partially substituted by bismuth in the Ca3-xBixCoO9+delta (x=0.00, 0.05, 0.10, 0.15, 0.20, and 0.30) system in order to determine how this substitution affects the thermoelectric and magnetic properties of the system. It was determined that the system had a positive thermopower, and thus the main carriers ...

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

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 experimental results were then used to calculate the thermoelectric figure of merit for each sample. ...

Thermoelectric properties of Ca2.95Bi0.05Co4−xFexO9+delta (0 < x < 0.15)

Thermoelectric materials are currently being researched as a source of energy in order to reduce carbon dioxide emissions. The efficiency of these materials depends on their Seebeck coefficient, electrical resistivity, and thermal conductivity, as well as the absolute temperature. Cobalt oxides (Ca3Co4O9+delta) ...
