Caronene

The scientists at the Germany’s Max Planck Institute, the Department of Materials Science and Engineering, University of Utah, and Tsinghua University, Beijing had created a Graphene transistor composed of 13 benzene rings. It has been named as Caronene. It is special because it shows an improved electronic band gap, a property which may help to overcome one of the central obstacles to applying Graphene technology for electronics.

Benzene has an hexagonal structure comprising 6 carbon atoms. But it is an insulating material. Caronene has 13 benzene rings arranged in a well defined shape. When these rings are joined together, the material behaves like a semiconductor and displays well defined on off properties of a transistor.
