  Title

  Graphene: electrons in the flatland

  Abstract

  Graphene, a one atom thick layer of graphite, was isolated only a few years ago and has generated a lot of interest in basic science and technology. Graphene is a semi-metal whose elementary excitations are Dirac fermions with very unsual electronic properties such as anomalous quantum Hall effect, absence of screening, strong sensitivity to disorder, just to mention some. Furthermore, the electronic properties of graphene can be manipulated with the use of external electrical and magnetic fields making of graphene a very flexible material for device applications. In this seminar I will review the basic properties of graphene and describe the latest developments in one of the fastest growing fields in condensed matter research.
