Effect of edge vacancies on localized states in semi-infinite zigzag graphene sheet
The effect of vacancies on the robustness of zero- energy edge electronic states in zigzag- type graphene layer is studied at different concentrations and distributions of defects. All calculations are performed by using the Green's function method and the tight- binding approximation. It is found that the arrangement of defects plays a crucial role in the destruction of the edge states. We have specified a critical distance between edge vacancies when their mutual influence becomes significant and affects markedly the density of electronic states at graphene edge.
