Abstract
The electrical conductivity of digenite (Cu2-xS) is measured at contro lled sulfur activities in the temperature range 475-650-degrees-C. A d efect model in digenite is proposed which is consistent with our condu ctivity data and non-stoichiometry data from literature. The observed conductivity temperature relationship is analysed to determine the con trolling mechanism for conductivity.
