Abstract
Electronic and ionic conductivities of liquid Cu-Se system have been measured as a function of concentration and temperature. The electronic conductivity, σe, in the system shows a broad minimum near the composition Cu2Se and the ionic conductivity, σi, has a maximum around this composition. In Se-rich region, a change from negative to positive temperature dependence of σe and a discontinuous jump in σi have been observed at a certain temperature. The relation between the electronic and ionic conductivities have quantitatively been discussed.
