Abstract
Graphene is a new two-dimensional material prepared succesfully in experiments several years
ago. It is a single layer of carbon atoms arranged in a hexagonal (honeycomb) lattice. The
two-dimensional nature of graphene leads to many intersting electronic, thermal, optical trans-
parency, and high mobility properties. One particularly interesting property of graphene is that
it exhibits the quantum Hall e ect at room temperature. In addition graphene is substantially
stronger than steel, and it is very stretchable
