主  题:Variable Coupling Strength of Silicene on Ag lll 

摘      要:We perform a scanning tunneling microscopy and spectroscopy study on the electronic structures of √3×√3- silicene on Ag(111). It is found that the coupling strength of √3×√3-silicene with the Ag-(111) substrate is variable in different regions, giving rise to notable effects in experiments. This evidence of decoupling or variable interaction of silicene with the substrate is helpful to in-depth understanding of the structure and clectronic properties of silieene.
