摘要
Atomic force microscopy (AFM) has been used to study the interface structure of stage-1 and stage-2 fluorine-graphite intercalation compounds (CXF) synthesized under the gaseous HF. The results obtained are summarized as follows; (1) It is difficult to prepare the atomically-flat surfaces of the stage-1 CXF by cleaving. (2) We have recognized a well ordered 2 x root 3 and 1 x root 3 superlattice structures of fluorine atoms with twofold symmetry on the cleaved surfaces of the stage-1 CXF synthesized from natural graphite. This suggests that the 1 x 1 ordered structure and the new 1 x root 3 superlattice structure of fluorine atoms coexist in the interface of the stage-1 CXF. (3) Only the graphitic surface structure has been observed on the cleaved surfaces of the stage-2 CXF. This suggests that the cleavage occurs at the graphite layer having the weak bonds preferentially. (4) We have found that the force between the tip of AFM and a sample surface for the intercalant layer of CXF is larger than that for the graphite layer.
