Abstract


Theoretical investigation of influence of external pressure on defects migration in the graphene layers has been performed. It has been shown that compression of structure along parallel direction and extension
along perpendicular direction to the vacancy migration decrease activation energy of vacancy migration. It leads to increasing of jump frequency. On the basis of derived results it is possible to create method allowing us to localize defects in the graphene structure without annealing up to the high temperatures.
