Abstract We present the observation of gold intercalation into the polycrystalline C 60 and c 70 thin films by a dry electrolysis of the electrode, detected by in situ and space resolved conductivity measurements at different temperatures and applied voltages. The time resistivity behavior is described on the basis of electric field stimulated diffusion of metal ions from the contact into the interstitials of crystal lattice. The resistivity minima correspond to a local formation of Au 3 C 60… CONTINUE READING
