Common band structure of graphene. For each of the momenta: p x and p y , several Brillouin zones [1] are considered, so the hexagonal structure can be seen clearly. The lower surface corresponds to the sign “–” in the formula (6) for the energy ε(p) and relates to the conduction band with normal dispersion. The upper surface corresponds to the sign “+” in this formula and relates to the conduction band with anomalous dispersion. Both zones take part in the conductivity
