The recent discovery of graphene, a two dimensional carbon crystal, has generated a lot of excitement in condensed matter community because of its unusual electronic properties as well as its potential applications.

I will present a detailed angle resolved photoemission spectroscopy study of the band structure and many body interactions in epitaxially grown graphene on SiC.

The evolution of the many body interaction and spectral function as function of layers is presented. We also show that due to the substrate, a gap in the electronic spectra can be induced at the Dirac point illustrating the great potential of graphene for next generation electronic devices.
