Title

Atomic site distributions in TiZnNi2Sb2 half-Heusler thermoelectric

Abstract

The aim of the experiment is to determine the distribution of Ti, Zn and Ni over the X (0, 0, 0) and Y (0.25, 0.25, 0.25) sites in the half-Heusler structure [Sb located at (0.5, 0.5, 0.5)], and to check for possible occupancy of a vacant site (0.75, 0.75, 0.75). Neutrons are vital because of the good scattering contrast for these elements (Zn: b = 5.7 fm, Ni: b = 10.3 fm and Ti b = -3.4 fm), which have next to no X-ray contrast. This composition is of interest as a possible thermoelectric with zT = 0.35 at 600 K. The results will go towards a PhD thesis that will be submitted by September 2023.
