Thermoelectric Properties of Nanostructured CeAl$_{3}$

Past investigations into the heavy fermion compound CeAl$_{3}$ reveal a complex low-temperature physics resulting from the strong hybridization of localized 4f states with delocalized conduction electrons. This phenomenon gives rise to unusual electronic, thermal, and magnetic properties. We investigate the low-temperature thermoelectric properties of this strongly correlated system for its potential application as a $p$-type Peltier cooling element. In our work, nanostructured samples of CeAl$_{3}$ have been prepared using dc hot-press method and evaluated for their thermoelectric properties. Effects of different hot-pressing temperatures on the nanostructure and the thermoelectric properties will be discussed. Our results on CeAl$_{3}$ will be compared with our previous work on CeCu$_{6}$.
