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…
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…
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…
