Graphene is an allotrope of carbon, whose structure is one-atom-thick planar sheets of sp2-bonded carbon atoms that are densely packed in a honeycomb crystal lattice. The term graphene was coined as a combination of graphite and the suffix -ene by Hanns-Peter Boehm, who described single-layer carbon foils in 1962. Graphene is most easily visualized as an atomic-scale chicken wire made of carbon atoms and their bonds. The crystalline form of graphite consists of many graphene sheets stacked together. Since its discovery, many other two-dimensional materials have appeared, including, to name a few, transition metal dichalcogenides, phosphorene, antimonene, magnetic CrI3, etc.
