摘要

The structure of silicene, the two-dimensional honeycomb sheet of Si, grown on Ag(111) was investigated by scanning tunneling microscopy (STM) and low-energy electron diffraction (LEED) combined with density functional theory (DFT) calculation. Two atomic arrangements of honeycomb configuration were found by STM, which are confirmed by LEED and DFT calculations; one is 4×4 and the other is √13 × √ 13R13.9° In the 4×4 structure, the honeycomb lattice remains with six atoms displaced vertically, whereas the √13 × 13R13.9° takes the regularly buckled honeycomb geometry.
