Graphene () is a variety of the element carbon which occurs naturally in small amounts. In graphene, the carbon forms a sheet of interlocked atoms as hexagons one carbon atom thick. The result resembles the face of a honeycomb. When many hundreds of graphene layers build up, they are called graphite.
Graphene is a form of carbon that exists as an incredibly thin sheet—just one atom thick—where the carbon atoms are arranged in a honeycomb-like pattern of interlocking hexagons. It occurs naturally in small amounts, and when many layers of it stack together, they form graphite.

Commonly known types of carbon are diamond and graphite. In 1947, the Canadian physicist P. R. Wallace suggested carbon could also exist in sheets. The German chemist Hanns-Peter Boehm and coworkers isolated single sheets from graphite, giving them the name graphene in 1986. In 2004, the material was characterized by Andre Geim and Konstantin Novoselov at the University of Manchester, England. They received the 2010 Nobel Prize in Physics for their experiments.
