Thermoelectric Transport Properties of <i>n</i>-Type Sb-doped (Hf,Zr,Ti)NiSn Half-Heusler Alloys Prepared by Temperature-Regulated Melt Spinning and Spark Plasma Sintering

Herein we report a significantly reduced lattice thermal conductivity of Sb-doped Hf<sub>0.35</sub>Zr<sub>0.35</sub>Ti<sub>0.3</sub>NiSn half-Heusler alloys with sub-micron grains (grain size of ~300 nm). Polycrystalline bulks of Hf<sub>0.35</sub>Zr<...
