Graphene
Hexagonal lattice made of carbon atoms
For the mobile operating system, see GrapheneOS.
Not to be confused with Graphite or Grapheme.
Graphene ()[1] is a carbon allotrope consisting of a single layer of atoms arranged in a honeycomb planar nanostructure.[2][3] The name "graphene" is derived from "graphite" and the suffix -ene, indicating the presence of double bonds within the carbon structure.
Graphene is known for its exceptionally high tensile strength, electrical conductivity, transparency, and being the thinnest two-dimensional material in the world.[4] Despite the nearly transparent nature of a single graphene sheet, graphite (formed from stacked layers of graphene) appears black because it absorbs all visible light wavelengths.[5][6] On a microscopic scale, graphene is the strongest material ever measured.[7][8]
The existence of graphene was first theorized in 1947 by Philip
