(a) Probability densities of the wave functions of the edge states labeled by A, B, C, D in Fig. 3(c), the inset is the schematics which indicate the propagation directions of the edge modes. (b) The calculated spin Chern numbers within the continuum Dirac model as a function of strain \(A\) with \({\lambda }_{so}=0.03{t}_{0}\). The GNR width is set to be 240 carbon atoms.
