Physical Review B, 83(4). http://dx.doi.org/10.1103/PhysRevB.83.0454141098-0121http://hdl.handle.net/20.500.12416/1180We critically discuss the stability of edge states and edge magnetism in zigzag edge graphene nanoribbons (ZGNRs). We point out that magnetic edge states might not exist in real systems and show that there are at least three very natural mechanisms-edge reconstruction, edge passivation, and edge closure-which dramatically reduce the effect of edge states in ZGNRs or even totally eliminate them. Even if systems with magnetic edge states could be made, the intrinsic magnetism would not be stable at room temperature. Charge doping and the presence of edge defects further destabilize the intrinsic magnetism of such systemseninfo:eu-repo/semantics/closedAccessAugmented-Wave MethodRibbonsEnergyArticle83410.1103/PhysRevB.83.045414
