Journal ArticleDOI
Silicene: Compelling Experimental Evidence for Graphenelike Two-Dimensional Silicon
Patrick Vogt,Patrick Vogt,Paola De Padova,Claudio Quaresima,José Avila,Emmanouil Frantzeskakis,Maria C. Asensio,Andrea Resta,B. Ealet,Guy Le Lay +9 more
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.
Journal ArticleDOI
Evidence of graphene-like electronic signature in silicene nanoribbons
Paola De Padova,Claudio Quaresima,Carlo Ottaviani,Polina M. Sheverdyaeva,Paolo Moras,Carlo Carbone,Dinesh Topwal,Bruno Olivieri,Abdelkader Kara,Hamid Oughaddou,Bernard Aufray,Guy Le Lay +11 more
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.
Journal ArticleDOI
Evidence of Dirac fermions in multilayer silicene
Paola De Padova,Patrick Vogt,Andrea Resta,José Avila,Ivy Razado-Colambo,Claudio Quaresima,Carlo Ottaviani,Bruno Olivieri,Thomas Bruhn,Toru Hirahara,Terufusa Shirai,Shuji Hasegawa,Maria C. Asensio,Guy Le Lay +13 more
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.
Journal ArticleDOI
sp2-like hybridization of silicon valence orbitals in silicene nanoribbons
TL;DR: In this article, reflection electron energy loss spectroscopy as a function of the electron beam incidence angle α was performed on silicene nanoribbons, and the spectra revealed the presence of two distinct loss structures attributed to transitions 1s→π∗ and 1 s→σ∗, according to their intensity dependence on α.
Journal ArticleDOI
Multilayer Silicene Nanoribbons
Paola De Padova,Osamu Kubo,Bruno Olivieri,Claudio Quaresima,Tomonobu Nakayama,Tomonobu Nakayama,Masakazu Aono,Guy Le Lay +7 more
TL;DR: This work reveals the growth of high aspect ratio, perfectly straight, and aligned silicon nanoribbons, exhibiting pyramidal cross section in multistacks of silicene, which is very promising for potential applications.
