WebJan 1, 2024 · Graphene, by definition, is an allotrope of carbon in the form of a 2D, atomic-scale, hexagonal lattice in which one atom forms each vertex with sp2 hybridization. As shown in Fig. 1-5, the length of the carbon–carbon bond is about 0.142 nm. There are three σ bonds in each lattice with strong connections forming a stable hexagonal structure. WebCarbon, the elementary constituent of graphene and graphite, is the 6th element of the periodic table. Its atom is, therefore, built from 6 protons, Aneutrons, and 6 electrons, where A= 6 and 7 yield the stable isotopes 12C and13C, respectively, and A= 8 characterises the radioactive isotope 14C.
