(color online) The schematic structure, Brillouin zone r-BZ, and band structure for the (1, 1) PGS are shown in panels (a), (b), and (c), respectively. Those for the (1, 3) PGS are presented in panels (d), (e), and (f), respectively. The Brillouin zone h-BZ corresponding to the primitive unit cell is also shown in panels (b) and (e) for comparison. The panels (g), (h), and (i) are the band structures of the antidot-patterned (5, 6), (5, 7), and (5, 8) germanene nanomeshes.
