| Popis: |
We have synthesized polycrystalline samples with nominal compositions La0.5Ca0.5MnO3-Agx (0 ≤ x ≤ 0.1) by solid state reaction method and studied thermoelectric properties within the temperature range of 300K to 800K. The electrical resistivity decreases with increasing temperature for all the samples. The Seebeck coefficient (S) increases gradually with temperature and negative sign of indicates n-type nature. The addition of silver causes a drastic reduction in electrical resistivity and significant enhancement in Seebeck coefficient. |
