Abstract

The electrical conductivity of digenite (Cu2-xS) is measured at controlled sulfur activities in the temperature range 475- 650°C. A defect model in digenite is proposed which is consistent with our conductivity data and non-stoichiometry data from literature. The observed conductivity temperature relationship is analysed to determine the controlling mechanism for conductivity.
