Electroluminescence of monolayer WS in a scanning tunneling microscope: the effect of bias polarity on the spectral and angular distribution of the emitted light
Ricardo Javier Peña Román}, Delphine Pommier, Rémi Bretel +12
Inelastic electron tunneling in a scanning tunneling microscope (STM) is used to generate excitons in monolayer tungsten disulfide (WS). Excitonic electroluminescence is measur…
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…
Plasmon scattering from holes: from single hole scattering to Young's experiment
Tao Wang, Elizabeth Boer-Duchemin, Geneviève Comtet +4
In this article, the scattering of surface plasmon polaritons (SPPs) into photons at holes is investigated. A local, electrically excited source of SPPs using a scanning tunnelling…
Silicon Sheets By Redox Assisted Chemical Exfoliation
Mohamed Rachid Tchalala, Mustapha Ait Ali, Hanna Enriquez +15
In this paper, we report the direct chemical synthesis of silicon sheets in gram-scale quantities by chemical exfoliation of pre-processed calcium di-silicide (CaSi2). We have used…
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…
Pseudospin rotation and valley mixing in electron scattering at graphene edges
Changwon Park, Heejun Yang, Andrew J. Mayne +5
In graphene, the pseudospin and the valley flavor arise as new types of quantum degrees of freedom due to the honeycomb lattice comprising two sublattices (A and B) and two inequiv…
