High resolution scanning tunnelling microscopy and extended x-ray-absorption fine structure study of the (533) silicide structure on Cu(001)
B. Lalmi, M. Chorro, R. Belkhou
Using low energy electron diffraction (LEED), scanning tunnelling microscopy (STM) and x-ray absorption spectroscopy (XAS) techniques, we have studied the first steps of silicon ad…
Formation and stability of a two-dimensional nickel silicide on Ni (111) an Auger, LEED, STM, and high-resolution photoemission Study
B. Lalmi, C. Girardeaux, A. Portavoce +3
Using low energy electron diffraction (LEED), Auger electron spectroscopy (AES), scanning tunnelling microscopy (STM) and high resolution photo-electron spectroscopy (HR-PES) techn…
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…
Silicene Structures on Silver Surfaces
Hanna Enriquez, Sébastien Vizzini, Abdelkader Kara +2
In this paper we report on several structures of silicene, the analog of graphene for silicon, on the silver surfaces Ag(100), Ag(110) and Ag(111). Deposition of Si produces honeyc…
Effect of Oxygen Adsorption on the Local Properties of Epitaxial Graphene on SiC (0001)
C. Mathieu, B. Lalmi, T. O. Mentes +5
The effect of oxygen adsorption on the local structure and electronic properties of monolayer graphene grown on SiC(0001) has been studied by means of Low Energy Electron Microscop…
Epitaxial Growth of a Silicene Sheet
Boubekeur Lalmi, Hamid Oughaddou, Hanna Enriquez +4
Using atomic resolved scanning tunneling microscopy, we present here the experimental evidence of a silicene sheet (graphene like structure) epitaxially grown on a close-packed sil…
