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

…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. In technical terms, graphene is a carbon allotrope consisting of a single layer of atoms arranged in a honeycomb planar nanostructure. The name…
