摘要：

Temperature (T) dependence of thermoelectric (TE) properties of Ca0.98La0.02MnO3 has been studied with in the temperature range of 300 K to 900 K. It is observed that the Seebeck coefficient (S) increases with increasing temperature. The negative sign of S indicates that CMO is an n-type TE material. Resistivity (rho) shows a metal-insulator type transition. The addition of Silver to these samples caused a reduction in the electrical resistivity of the samples, where as the Seebeck coefficient remained almost constant, desirable for thermoelectric materials.
