Abstract: Due to the two graphene layers displacement at a certain angle relative to each other the different types regions of crystallographic (AA- and AB-packages) appears in the structure. At the same time, this structure has a geometric pattern looks like a “moiré” and their energy spectrum has alternation of the energy gap and gapless regions. The spatial period of the energy changing parameters is about ten nanometers order, therefore, the regions can be considered as a superlattice. In addition, at the areas boundaries, the relaxation occurs, which affects the region size and the energy structure in them. In this work, we numerically study the layers disorientation angle influence, the energy gap parameter on the transport characteristics.
