Collapsed Deposition of Accelerated C-60 Beam on Solid Surface(II) STM Studies
- 化学化工－已发表论文 
Mass-selected C-60 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 planer structure on the solid surface, but the collapsed species were not dissociated and well oriented on the surface. Both positive and negative C-60 ions were observed in the desorption mass spectra, confirming that the species collapsed on the solid surface are still the C-60 clusters.
