▎ 摘 要
The band structure, electronic structure and density of states of the Delta nitrogen-doped armchair-edge graphene nanoribbons (AGNRs) were investigated under compressive strain by means of an extension of the Extended Huckel method. The results indicate that the Nitrogen-doped graphene nanoribbons (N-AGNRs) system can show a good elastic behavior under 16% compressive strain. Meanwhile, N-AGNRs can maintain the metallic under compressive strain between 0% and 20%. Further analysis suggests that compressive strain induced electronic states nonlocal phenomenon.
