Thermoelectric Properties of RE(x)Ce(1-x)Pd3 (RE=Y, La(0.5)Y(0.5') Nd).

Abstract

The intermediate valent compound CePd3 has an unusually large thermoelectric power (from 100-300 K), which is interesting from the perspective of thermoelectric cooling devices. To optimize the thermoelectric properties, we have investigated rare earth substituted samples of the form RE(x)Ce(1-x)Pd3 where RE=Y, La(0,5)Y(0.5'),Nd. We have found that the intermediate valent state is highly dependent on the nature of the rare earth dopant and in particular to any local strains or bond distance changes. With Nd dilution, a small enhancement of the thermoelectric power factor alpha(2)/rho is observed.
