(Color online) Wave functions at the Gamma point of defective ZGNRs. Wave functions at the Gamma point associated with the LUES above the CNP (top Panel) and the HOES below the CNP (bottom Panel) for ZGNR with no defects (a, d), symmetric SW defects (b, e) asymmetric SW defects (c, f). Dark gray (blue online) and light gray (red online) colors correspond to the opposite signs of the wave function.
