(color online) The D_6h defect formed by contracting the Ge–Ge bonds by 3.5% of the grey (yellow online) hexagon (a) and the corresponding band structure along the Y′–Γ–Y path (b). The corresponding band-decomposed charge densities at isovalue of ∼ 0.01 e/Å³ for the split π_a1, π_a2, π_z1, and π_z2 bands are shown in panel (c).
