| Top views [(a) and (b)] and side views [(c) and (d)] of two mirror-symmetrical silicene sheets on Ag (111) surface, obtained from DFT optimization in the case of lattices of both silicene and silver substrate having identical directions. (e) Top views of superposition of structures in panels (a) and (b). Color code: Blue large balls, yellow small balls, and red small balls denote Ag atoms, Si atoms in the lower layer, and Si atoms in the higher layer, respectively. The red triangles denote the units of silicene in (a) and (b) structures. (f) Scanned transition barrier between two symmetrical counterparts.[ 18 ] |
