Abstract

The compositional dependence of the crystal structure and lattice thermal conductivity in the Cu₃SbSe₄-Cu₃SbS₄ system has been studied. The lattice parameters of the Cu₃SbSe _4-xS_x compounds decrease linearly with x, and the tetragonal structure (space group 142m no. 121) of the end compounds is maintained at all compositions. The lattice thermal conductivity is much lower than that predicted by a simple rule of mixtures, which is typical for a solid solution. The Debye model produces a very reasonable fit to the experimental lattice thermal conductivity data when phonon scattering due to atomic mass and size differences between Se and S is taken into account. Compounds in this series are likely to improve upon the thermoelectric performance of Cu ₃SbSe₄, which has shown ZT = 0.72 when optimized.
