Enhanced thermoelectric performance in TiNiSn-based half-Heuslers

arXiv:1301.0419 · doi:10.1039/c2cc37121a

Abstract

Thermoelectric figures of merit, ZT > 0.5, have been obtained in arc-melted TiNiSn-based ingots. This promising conversion efficiency is due to a low lattice thermal conductivity, which is attributed to excess nickel in the half-Heusler structure.
