| Calculated band structures of (a) 4 × 4 and (b) . The gradient bar manifests the contribution of Si 3p z orbital to each branch. The darker the region, the higher the contribution in the region is. Panels (c) and (d) indicate the Brillouin zones (BZs) of 4 × 4 and phases together with the BZs of Ag (111) 1 × 1 and silicene 1 × 1. The yellow hexagons in panels (c) and (d) represent the BZs of 4 × 4 and phases, respectively. The blue hexagons refer to the BZs of corresponding 1 × 1 honeycomb lattice in each structure. The black hexagons denote the BZs of the Ag (111) surface. Γ 1, K 1, and M 1 are the highly symmetric points in the BZ of silicene 1 × 1 and Γ 2, K 2, and M 2 are the highly symmetric points in the BZ of 4 × 4 or . |
