(color online) (a) The schematic structure for the defect introduced by contracting the highlighted hexagon. (b) The band structure for the (3,5) superlattice patterned by such defect. The split bands along ΓY path are marked with , , , and at Y point. (c) The band decomposed charge densities at iso-value of for the split bands.
