摘要：

Non-contact atomic force microscopy (NC-AFM) was used to study thin films of C-60 on Au(111). After observing the Au(111) 23 x root3 reconstruction, 2-3 monolayers Of C60 were deposited onto the An surface. The close-packed C-60 surface was imaged by NC-AFM with molecular resolution. Enhanced corrugation and a stretching of the C-60 lattice were observed at step edges. Based on a calculation of the force required to displace an edge molecule, it is proposed that the edge effects are a result of tip-induced displacements of edge molecules. While imaging small clusters of C-60, some molecules were removed, leading to structural rearrangements of the clusters.
