✦ Synopsis
We have investigated
the surface structure of stage-l CuCI,-and FeCI,-graphite intercalation compounds (GICs) by atomic force microscopy.
For both GICs, the atomically flat terrace-step structures have been easily obtained by cleaving and, on the terraces, interesting incommensurate superlattices have been observed. In the case of CuCI,-GIG, surface structure of intercalated molecules was very similar to the bulk structure.
For FeCI,-GIC, it is noteworthy that surface reconstruction or rearrangement of intercalated molecules has been found. We have also found long-period super-lattice structures for both GICs. The origins of these superlattices are discussed.
