Abstract
NbFeSb-based alloys are promising
p
-type half-Heusler materials with excellent thermoelectric performance, thermal stability, and naturally abundant constituent elements. Alloying and doping are powerful techniques for enhancing the thermoelectric properties of half-Heusler materials. This study experimentally investigated the effects of V alloying in NbFeSb codoped with Ti, Zr, and Sn. As.....

DOI:
https://doi.org/10.3365/KJMM.2022.60.3.213
Abstract
Half-Heusler (HH) thermoelectric materials are promising for mid- to high-temperature applications, and
M
NiSn (
M
= Ti, Zr, Hf) is a representative n-type HH alloy. In general, the
M
sites are mixed with isoelectronic elements Ti, Zr, and Hf, to lower the lattice thermal conductivity, and the Sn sites are doped.....

For alloying, a conventional induction melting technique was employed rather than arc melting, for mass production compatibility, and the thermoelectric properties of the materials were analyzed. The maximum dimensionless.....
