Interest in graphene appears endless at the moment, with most interest related to the “simple” Dirac particle like electronic structure. On the surface this simplicity would appear to make investigations into the electronic structure less than exciting. On the contrary the simple nature of the underlying electronic structure allows detailed analysis of the quasi-particle, hybridization and substrate interaction features observed in photoemission spectroscopy. This allows for a new understanding of the physics behind photoemission, and has resulted in the observation of new types of quasi-particle bands. To this end angle resolved photoemission spectra obtained from graphene on a range of substrates is presented and used to investigate these interactions and reveal the underlying processes.
