Abstract

The electron and phonon transports in CaMnO₃ and in one of its Bi-doped counterparts, namely, Bi_0.03Ca_0.97MnO₃, are investigated using the thermoelectric transport measurements and first-principles calculations. We find that antiferromagnetic insulator CaMnO₃ breaks the Wiedemann–Franz law with the Lorenz number reaching four times that of ordinary metals at room temperature. Bismuth doping reduces both the electrical resistivity and Seebeck coefficient of CaMnO₃; thus, it recovers the Wiedemann–Franz law behavior. In addition, Bi_0.03Ca_0.97MnO₃ possesses a shorter phonon lifetime according to the transport measurements. As a result, Bi_0.03Ca_0.97MnO₃ exhibits superior thermoelectric properties over pristine CaMnO₃ owing to the lower thermal conductivity and electrical resistivity.
