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.
Journal ArticleDOI
24 h stability of thick multilayer silicene in air
Paola De Padova,Carlo Ottaviani,Claudio Quaresima,Bruno Olivieri,Patrizia Imperatori,Eric Salomon,Thierry Angot,Lucia Quagliano,Claudia Romano,Alessandro Vona,Maurizio Muniz-Miranda,Amanda Generosi,Barbara Paci,Guy Le Lay +13 more
TL;DR: In this paper, the authors measured the surface properties of thin epitaxial multilayer silicene films with a root 3 x root 3R(30 degrees) surface structure, as measured by Auger electron spectroscopy.
