Thin Au–C60 films with global composition AuxC100−x (x between 0.35 and 4.50 at.%) were prepared by vacuum co-deposition and investigated by X-ray diffraction, EDS, XTEM and electrical transport. Evidence indicated the formation of distorted nanocrystalline Au, presumably stabilized by interface electron transfer into C60 LUMO. Electrical results are interpreted in the frame of the dominant current model, with a continuous density of localized states induced by Au in the C60 gap. There is also evidence for variable range hopping at low temperatures.
