Wave dispersion along the zigzag and armchair directions for a (8,0) GNR with length 15.854 nm. (a) Continuous green line is referred to the Hamiltonian minimized versus d. Continuous red line is for the Hamiltonian minimized both for d and l. (b) Comparison of wave dispersions along the zigzag direction (continuous blue line) and armchair (continuous red line). The Hamiltonians are minimized for d only.
