摘要：

The impact of Ag clusters on graphite is studied with the scanning tunneling microscope. Ag-n(-) clusters (n = 1, 3, 5, and 7) are projected at normal incidence to the surface at constant energy per cluster ion (1.5 keV/ion). We observe protrusions with diameters of similar to 2.5 nm on the surface of graphite which we attribute to bumps in the graphite surface layer. We show evidence that the positions of the Ag atoms implanted during cluster bombardment remain highly localized. (C) 1998 American Institute of Physics. [S0021-8979(98)06002-2].
