Abstract The in situ direct-current conductance behaviors of Cu/ C60 nano-scale granular films have been investigated experimentally. The results show that the incorporation of Cu into C60 greatly increases the conductance of the film. The orientational phase transition that exists in pure C60 single crystals still retains in the Cu/C60co-evaporated films, while the transition temperature range is significantly widened. The interactions between the nano-scale Cu clusters and C60 grains are discussed.
