TL;DR: Here it is provided compelling evidence, from both structural and electronic properties, for the synthesis of epitaxial silicene sheets on a silver substrate, through the combination of scanning tunneling microscopy and angular-resolved photoemission spectroscopy in conjunction with calculations based on density functional theory.

TL;DR: In this article, the self-aligned silicon nanoribbons on Ag(110) with honeycomb, graphene-like structure were observed by scanning tunneling microscopy (STM) and ab initio calculations based on density functional theory.

TL;DR: In this article, the electronic properties of straight, 1.6 nm wide, silicene nanoribbons on Ag(110), arranged in a one-dimensional grating with a pitch of 2 nm, whose high-resolution scanning tunneling microscopy images reveal a honeycomb geometry.

TL;DR: In this paper, the authors measured a cone-like dispersion at the Brillouin zone center due to band folding in multilayer silicene, and showed that the π* and π states meet at ∼ 0.25ÕeV below the Fermi level.

TL;DR: This work presents scanning tunneling microscopy (STM) and non-contact Atomic Force Microscopy (nc-AFM) observations of the major structures of single layer and bi-layer silicene in epitaxy with Ag(111) and gives support to the conjectured possible existence of less stable, ~2% stressed, silicenes domains in the first layer.
