A single carbon layer of the
graphite structure, describing its nature by analogy to a polycyclic aromatic hydrocarbon
of quasi infinite size.
Note:
Previously, descriptions such as
graphite layers, carbon layers or carbon sheets have been used for the term graphene. Because
graphite designates that modification of the
chemical element carbon, in which planar sheets of carbon atoms, each atom bound to three neighbours
in a honeycomb-like structure, are stacked in a three-dimensional regular order, it
is not correct to use for a single layer a term which includes the term
graphite, which would imply a three-dimensional structure. The term graphene should be used
only when the reactions, structural relations or other properties of individual layers
are discussed.
