Introduction

What is graphene?

In one sense graphene is an unrolled carbon nanotube, or a flattened buckyball. Graphene is a material made of carbon atoms arranged in a hexagonal, “honeycomb” lattice. It is similar to graphite, except that it is only one sheet of atoms thick! A square meter of graphene weighs less than a milligram. Since its discovery, graphene has garnered significant attention for its electronic, thermal, optical, mechanical, and other properties. There is currently a huge amount of research into the properties and applications of graphene, and one Nobel Prize has been awarded (the 2010 Prize in Physics) for research into its properties.
