The structural and electrical properties of liquid copper selenide

Abstract

The partial structure factors and radial distribution functions for liquid CuSe have been determined by the isotopic substitution technique and the results compared with those from an earlier study of liquid CuTe. It is shown that, whereas the underlying ionic configuration of CuTe can be written as Cu⁺Te⁻, for CuSe the situation is more complicated in that some of the anions may aggregate to form stable pairs. In addition, the electrical conductivity and thermoelectric power has been measured for CuSe and Cu₂Se and at two intermediate compositions.
