From: Helical edge states and edge-state transport in strained armchair graphene nanoribbons
Edge-state band structures and probability densities of the edge-state wave functions of zigzag (a,b) and armchair (c–f) GNRs for \(\{{t}_{so}=0.01{t}_{0},{t}_{R}=0.02{t}_{0},M=0.01{t}_{0}\}\). The strain is set as ε = 0 for (a–d); and ε = 0.18 for the other figures. The GNR width is set to be 240 carbon atoms.
