Abstract

We report the thermal conductivity and the Seebeck coefficient of polycrystalline samples of Cu₆O₈YCl_1-xBr_x. The lattice constant a linearly increases with increasing Br^- concentration x, indicating an expansion of the Cu₆O₈ cage. At 350 K, the thermal conductivity κ is small and undergoes very little change with x, suggesting the existence of an anharmonic vibration. On the other hand, the Seebeck coefficient S is enhanced by substituting Br^- for Cl^-. These facts indicate that the thermoelectronic properties are sensitive to the Cu₆O₈ cage size in the Cu₆O₈YCl system.
