In practical applications of graphene-based electronic devices, they may have some pore defects under energetic particle bombardment, or chemical corrosion, which will inevitably affect their electrical properties. These problems have recently aroused great concern and interest. In this paper, we systematically study the influence of shape (tripartite, tetragonal and hexagonal) of hole defect on the electrical property of zigzag graphene nanoribbon (ZGNR). The results show that the influence of the shape of the pore defects on the conductance and current characteristics of ZGNRs is significant, whicl may result from electron scattering for the different shapes of the poredefect boundary. In addition, due to defects in suspension adsorbed hydrogen or nitrogen atoms, caused by defects of the pore shape changes, it also affects the electrical properties of ZGNRs. This study will supply valuable theoretical guidances for graphene-based electronic device failure analysis and the design of the graphene pore structure.
