Like graphite, graphene is a pure carbon modification whose structure consists of two-dimensional sheets of aromatic carbon. The individual carbon atoms are hexagonally arranged and form a wrinkled surface.

The first synthesis of graphene was made in the late 19th century, unfortunately without any precise characterization.

Based on its promising properties, the general interest on graphene recently increased rapidly. After fullerenes in 1995 and carbon nanotubes in 2000, graphene has become the hype carbon material in physical science. In 2004 graphene has been studied again by the physicists Andre Geim and Konstantin Novoselov. Finally in 2010, they got the Nobel Prize in Physics for their characterisation of graphene and the derivation method of its Special physical properties.
