Using atomic resolved scanning tunneling microscopy, we present here the experimental evidence of a silicene sheet (graphenelike structure) epitaxially grown on a close-packed silver surface [Ag(111)]. This has been achieved via direct condensation of a silicon atomic flux onto the single-crystal substrate in ultrahigh vacuum conditions. A highly ordered silicon structure, arranged within a honeycomb lattice, is synthesized and present two silicon sublattices occupying positions at different… Expand

TLDR
The calculated STM images match the experimental ones, hinting to a possible new Si structure, mediated by the Ag substrate, and the observed new electronic states near the Fermi level were reproduced by the calculations and attributed to a confinement/hybridization tandem. Expand
