Silicene nanoribbons on an insulating thin film
Khalid Quertite, Hanna Enriquez, Nicolas Trcera +10
Silicene, a new two-dimensional (2D) material has attracted intense research because of the ubiquitous use of silicon in modern technology. However, producing free-standing silicen…
Phosphorus Pentamers: Floating Nanoflowers form a 2D Network
Wei Zhang, Hanna Enriquez, Yongfeng Tong +6
We present an experimental investigation of a new polymorphic 2D single layer of phosphorus on Ag(111). The atomically-resolved scanning tunneling microscopy (STM) images show a ne…
Tip-induced oxidation of silicene nano-ribbons
Mohammed Rachid Tchalala Hanna Enriquez, Azzedine Bendounan, Andrew J. Mayne +4
We report on the oxidation of self-assembled silicene nanoribbons grown on the Ag(110) surface using Scanning Tunneling Microscopy and High-Resolution Photoemission Spectroscopy. T…
Compelling experimental evidence of a Dirac cone in the electronic structure of a 2D Silicon layer
S. Sadeddine, H. Enriquez, A. Bendounan +7
The remarkable properties of graphene stem from its two-dimensional (2D) structure, with a linear dispersion of the electronic states at the corners of the Brillouin zone (BZ) form…
Epitaxial Synthesis of Blue Phosphorene
Wei Zhang, Hanna Enriquez, Yongfeng Tong +6
Phosphorene is a new two-dimensional material composed of a single or few atomic layers of black phosphorus. Phosphorene has both an intrinsic tunable direct band gap and high carr…
Combined AFM and STM measurements of a silicene sheet grown on Ag(111) surface
Zsolt Majzik, Mohamed Rachid Tchalala, Martin Švec +7
In this Letter, we present the first non-contact atomic force microscopy (nc-AFM) of a silicene on silver (Ag) surface, obtained by combining non-contact atomic force microscopy (n…
Adsorption of silicon on Au(110): an ordered two dimensional surface alloy
Hanna Enrique, Andrew Mayne, Abdelkader Kara +9
We report on experimental evidence for the formation of a two dimensional Si/Au(110) surface alloy. In this study, we have used a combination of scanning tunneling microscopy, low…
Formation of one-dimensional self-assembled silicon nanoribbons on Au(110)-(2x1)
Mohamed Rachid Tchalal, Hanna Enriquez, Andrew J. Mayne +10
We report results on the self-assembly of silicon nanoribbons on the (2x1) reconstructed Au(110) surface under ultra-high vacuum conditions. Upon adsorption of 0.2 monolayer (ML) o…
