Query: Examining the thermal conductivity of half-Heusler alloy TiNiSn by
  first-principles calculations   The thermoelectric properties of half-Heusler alloy TiNiSn have been studied
for decade, however, theoretical report on its thermal conductivity is still
little known, because it is difficult to estimate effectively the lattice
thermal conductivity. In this work, we use the ShengBTE code developed recently
to examine the lattice thermal conductivity of TiNiSn. The calculated lattice
thermal conductivity at room temperature is 7.6 W/mK, which is close to the
experimental value of 8 W/mK. We also find that the total and lattice thermal
conductivities dependent temperature are in good agreement with available
experiments, and the total thermal conductivity is dominated by the lattice
contribution. The present work is useful for the theoretical prediction of
lattice thermal conductivity and the optimization of thermoelectric
performance.
