Figure 4.

Conductance vs Energy for the junction shown in Figure 1, a using first nearest-neighbour parameters and b using third nearest-neighbours parameters. Dotted lines are for N = 13 armchair nanoribbon, solid lines are for ideal metal/semiconductor junctions, dotdash lines and dash lines are for junctions with a single defect type A (triangle in Figure 1) and type B (rectangle in Figure 1) respectively.
