A review of the growth and structures of silicene on Ag (111) |
Summary of the atomic structural models proposed previously for the silicene/Ag (111) superstructure. Below each ball model is its corresponding STM simulation result with partial superimposition. Panels (a) and (c) are after Ref. [ 13 ], (b) after Ref. [ 21 ], (d) after Ref. [ 51 ], (e) after Ref. [ 52 ]. (h) Schematic illustration showing two sets of 13 × 13 unit cell with rotational angles of ±13.9° from the direction (adapted from Ref. [ 38 ]). |
