This also implies that …
Graphene is a single layer (monolayer) of carbon atoms, tightly bound in a hexagonal honeycomb lattice. It is an allotrope of carbon in the form of a plane of sp2-bonded atoms with a molecular bond length of 0.142 nanometres. Bonding Three of the four outer-shell electrons of each atom in a graphene sheet … See more Graphene is an allotrope of carbon consisting of a single layer of atoms arranged in a hexagonal lattice nanostructure. The name is derived from "graphite" and the suffix -ene, reflecting the fact that the See more Electronic Graphene is a zero-gap semiconductor, because its conduction and valence bands meet at the Dirac points.
