Effect of next-to-nearest neighbor hopping on electronic properties of graphene
In the tight-binding approximation, we take into account the next-to-nearest neighbor hopping in graphene that leads to nonrelativistic-like corrections in its low energy spectrum. The electronic density of states in a magnetic field is found and the fan diagram is plotted, which interpolates betw...

| description |
In the tight-binding approximation, we take into account the next-to-nearest neighbor hopping in
graphene that leads to nonrelativistic-like corrections in its low energy spectrum. The electronic density of
states in a magnetic field is found and the fan diagram is plotted, which interpolates between those for the
relativistic and nonrelativistic limiting cases. It is shown that the Berry phase for the system under consideration
coincides exactly with its value for the relativistic system.
