Effects of the Fe/Ni ratio in double half-Heusler composition HfFe<sub>1−<i>x</i></sub>Ni<sub><i>x</i></sub>Sb
The adjustment of the Fe/Ni ratio in the double half-Heusler composition HfFe x Ni 1− x Sb leads to a p-type to n-type transition. The thermoelectric figures of merit zT = 0.36 and 0.22 at 950 K for n- and p-type, respectively, were demonstrated.
