C60 molecule was adsorbed on the Au(111)surface and irradiated with UV light.The coalescence under the UV radiation was followed by STM in situ. According to the STMobservation, the coalesced products have larger cages and finally form a film.
Mass-selected C60 beam produced by laser ablation was accelerated and bombarded the (0001) surface of highly oriented pyrolitic graphite and (111) surface of gold single crystal. The samples were characterized by STM. The STM images showed that, the deposited species collapsed and formed planar structure on the solid surface, but the collapsed species were not dissociated and well oriented on the surface. Both positive and negative C60 ions were observed in the desorption mass spectra, confirming that the species collapsed on the solid surface are still the C60 clusters.
