Effect of substitutions on the thermoelectric figure of merit of half-Heusler phases at 800°C

The merit of thermally stable MNiSn ( M = Ti , Zr, Hf) half-Heusler phases, as n -type thermoelectric materials, for high-temperature power generation has been examined. Sb doping at the Sn site is shown to increase both the figure of merit, Z T , and the temperature at which Z T is maximized. The b...
