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…

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.

Burning match oxidation process of silicon nanowires screened at the atomic scale.
TLDR
This work investigates the oxidation of straight, massively parallel, metallic Si nanowires and identifies four new oxidation states on the oxidized part, which show a gap opening, thus revealing the formation of a transverse internal nanojunction.
