From: Helical edge states and edge-state transport in strained armchair graphene nanoribbons

Probability density across the single layer armchair GNR of the edge states in the presence of different intrinsic SOC and strain \({\lambda }_{so}=0\) and A = 0 (a), \({\lambda }_{so}=0\) and A = 0 (b), \({\lambda }_{so}=0.2{t}_{0}\) and A = 0 (c), and \({\lambda }_{so}=0.02{t}_{0}\) and \(A=0.06{t}_{0}\) (d). The GNR width is set to be 240 carbon atoms.
