Conclusion
With properly presented terminal protections and carefully arranged unit cell, cluster based tight bonding approximation is capable of simulating bulk properties of infinite GNRs.
Edge state plays a dominant role in GNR transport properties, and the presence of edge defects might greatly reduce the tunneling probability.
Conductance of GNRs with edge defects might be tunable by transverse electrostatic fields, which is primarily induced by electron-hole polarization along ribbon edges and the greatly enhanced potential barrier on edge defects.
