Summary, etc. |
<strong>The rare earths doped Ca<sub>0.95</sub>RE<sub>0.05</sub>MnO<sub>3</sub><sub> </sub>(RE=Pr, Eu, Tb) oxide bulk materials are fabricated and the effects of rare earths doping within low content on the thermoelectric transport properties of the CaMnO<sub>3</sub> oxide have been investigated. The results show that all doped oxide bulk materials are single phase with consolidated microstructure. The electrical resistivity is remarkably reduced on account of electron carrier density and mobility enhancement. The Seebeck coefficient is simultaneously reduced and the total thermal conductivity is decreased due to phonon thermal conduction confinement. The thermoelectric figure of merit <em>ZT</em> is improved with peak values of 0.12, 0.12 and 0.09 at 973 K for the Pr, Eu and Tb doped CaMnO<sub>3</sub> oxide materials, respectively, which are very much higher than that of the undoped oxide material.</strong> |
