Title: Electrochemical Studies on the Electron Disorder in Cuprous Selenide

At 435°C the homogeneity range of cuprous selenide extends from a Cu/Se ratio of 1.998 to a value lower than 1.860. Analysis of the experimental data shows that the change of the chemical potential of copper by a change of the composition is only given by a change of concentration of the defect electrons or of the quasifree electrons. From these studies, the energy gap in coprous selenide is at least 0.37 eV.Read More
