Conductance fluctuation for nitrogen-doped and vacancy-damaged AGNRs. Conductance fluctuation σ as a function of the energy E for a nitrogen-doped N
a = 45 AGNR (solid line), a nitrogen-doped N
a = 47 AGNR (dashed line), and a vacancy-damaged N
a = 47 AGNR (point) with fixed length: L~0.21 μm. Plotted values represent statistical averages over more of 500 equivalent replicas of the system. Charge neutrality points of pure and defected systems are aligned at E = 0 in the figure.
