    • These level positions are obtained by the 216-site cell calculation. The calculated band gap in this system containing a vacancy is 1.1 eV which is larger than the LDA band gap (0.5 eV). This is due to the smaller cutoff energy (6 Ry). When we increase the cutoff energy to 10 Ry, the band gap is reduced by 0.3 eV. The cutoff energy of 6 Ry is not enough for complete convergence on the band gap, but the results presented in this paper are not sensitive to the quantitative value of the band gap.

    • The different behavior of the wave function along the chains A and B can be understood in terms of the different backbond extension over the second-neighbor sites.
