Group-IV graphene- and graphane-like nanosheets
We performed a first principles investigation on the structural and
electronic properties of group-IV (C, SiC, Si, Ge, and Sn) graphene-like sheets
in flat and buckled configurations and the respective hydrogenated or
fluorinated graphane-like ones. The analysis on the energetics, associated with
the formation of those structures, showed that fluorinated graphane-like sheets
are very stable, and should be easily synthesized in laboratory. We also
studied the changes on the properties of the graphene-like sheets, as result of
hydrogenation or fluorination. The interatomic distances in those graphane-like
sheets are consistent with the respective crystalline ones, a property that may
facilitate integration of those sheets within three-dimensional nanodevices
