We start by exploring its crystalline properties, and then its electronic properties by using the tight-binding model. We verified that the graphene exhibits a linear electronic band dispersion at the K (K′) point, where the electrons behaves as Dirac’s particles. After that, we search to probe these theoretical considerations by experimental means studying the Raman spectrum of graphene.Attribution-NonCommercial-ShareAlike 3.0 Brazilhttp://creativecommons.org/licenses/by-nc-sa/3.0/br/FísicaGrafenoDispersão LinearCone de DiracEspectro RamanGrapheneLinear dispersionDirac coneRaman spectrumbachelorThesis
