Spontaneous twinning as an accommodation mechanism in monolayer graphene

We present numerical evidence that twinning operates as an accommodation and relaxation mechanism in graphene. We show that twins may arise spontaneously in graphene layers containing arrays of dislocations and that twinning results in a significant reduction in energy. We verify that the twinning r...
