Abstract

We report the effects of HfO2 nanoparticles as inclusion to the Zr0.5Hf0.5Ni0.8Pd0.2Sn0.99Sb0.01 half-Heusler matrix on the thermoelectric properties. X-ray powder diffraction and transmission electron microscopy were employed for the phase identification and microstructure characterization of the composites. The transport properties are mainly discussed with regards to the microstructure details.
