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.

Layers of graphene stacked on top of each other form graphite, with an interplanar spacing of 0.335 nanometres. It is the thinnest compound known to man at one atom thick, the lightest material known with 1 square meter coming in at around 0.77 milligrams. It is the strongest compound discovered between 100-300 times stronger than steel.



Uses
Optoelectronics, manufacture of photovoltaic cells, composite structures and in energy storage systems to increase electron mobility.
