摘要：

The structural and electronic properties of silicene nanosheets epitaxially grown on Ag(111) are systematically investigated by combining scanning tunneling microscopy and scanning tunneling spectroscopy. By carefully tuning the growth parameters, complex 2D silicon structures are obtained, which evidence the presence of corrugated silicene domains. Local modifications of the density of states are observed throughout reconstructed silicene domains and are attributed to the symmetry breaking induced by the interactions with the Ag lattice, in analogy with the case of graphene.
