noun. A monolayer of carbon atoms having a hexagonal lattice structure and constituting a basic structural element of graphite, fullerenes, and carbon nanotubes.

noun. Any polycyclic aromatic hydrocarbon having the structure of part of a layer of graphite.

noun. An arbitrarily large-scale, one-atom-thick layer of graphite, an allotrope of carbon, that has remarkable electric characteristics.

"A single carbon layer of the graphitic structure can be considered as the final member of the series naphthalene, anthracene, coronene, etc. and the term graphene should therefore be used to designate the individual carbon layers in graphite intercalation compounds."
