Title: Enhanced thermoelectric properties of n-type NbCoSn half-Heusler by improving phase purity

Abstract

In this paper, we report the thermoelectric properties of NbCoSn-based n-type half-Heuslers (HHs) that were obtained through arc melting, ball milling, and hot pressing process. With 10% Sb substitution at the Sn site, we obtained enhanced n-type properties with a maximum power factor reaching ~35 μW cm-1 K-2 and figure of merit (ZT) value ~0.6 in NbCoSn0.9Sb0.1. The ZT is doubled compared to the previous report. In addition, the specific power cost ($ W-1) is decreased by ~68% comparing to HfNiSn-based n-type HH because of the elimination of Hf.
