Title: dark electric conductivity Long Title: IUPAC Gold Book - dark electric conductivity DOI: 10.1351/goldbook.08788 Status: current Definition Electric conductivity of a material in the dark where the free charge-carrier photogeneration is excluded. Note The dark electric conductivity of a material in thermal equilibrium is proportional to the product of the concentration of free charge carriers and the charge carrier mobility.
