(color online) Localized states in an armchair BN nanoribbon supercell with the line defect (). The size of the supercell is set to be N = 23, 2M = 16. Panel (a) shows the wavefunction of the localized state with p = 8 in the 1D-supercell model, panel (b) the electron density distribution of the localized state with p = 8 in the 2D-TB model, panel (c) the wavefunction of the localized state with p = 9 in the 1D-supercell model, and panel (d) the electron density distribution of the localized state with p = 9 in the 2D-TB model.
