Electronic band structures of a zigzag GNR with n = 8 C chains under different conditions: a axial tension ε = 5%, b stress-free ε = 0, and c axial compression ε = −5%. The spatial distribution of the spin density of the edge states for the same zigzag GNR are given in d for VB edge state and e CB edge state. The red and blue colors represent the spin-up and spin-down orientations, respectively. The isosurface level of charge densities is 0.01 e/Å
