Graphene is a layer of carbon atoms arranged in a honeycomb lattice. In 2004, Andre Geim and Konstantin Novoselov made a revolutionary breakthrough as they were able to isolate graphene giving rise to a cascade of experiments that revealed its unique electronic properties. Electron interaction in graphene systems plays a prominent role in their electronic transport properties since, at the Fermi-level, the ground state of the system will be determined by the interplay of the energy minimization between the band and Coulomb energy as their magnitude is comparable. This work done on this thesis focuses in the study of the effect of electron-electron interactions in the electronic transport properties of Bernal-stacked graphene multilayers at low energies.
