Abstract
The temperature dependence of the thermopower, electrical resistivity, and thermal conductivity were explored for the solid solution obtained from the parent Kondo insulator While is a semiconductor with a small activation energy and a relatively large thermopower ( at 300 K), is a simple metal with a typically low thermopower at 300 K). The thermoelectric figure of merit ZT of the solid solution was found to be maximized at The maximum ZT of 0.12 at approximately 230 K, however, is too small to be useful in thermoelectric applications.
