Nanocrystalline gold in Au-doped thin C-60 films
Thin Au-C-60 films with global composition AuxC100-x (x between 0.35 and 4.50 at.%) were prepared by vacuum co-deposition and investigated by X-I ay diffraction, EDS, XTEM and electrical transport. Evidence indicated the formation of distorted nanocrystalline Au, presumably stabilized by interface electron transfer into C-60 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.
