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.

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