Transition from silicene monolayer to thin Si films on Ag(111): comparison between experimental data and Monte Carlo simulation

Autor: Alberto Curcella, Romain Bernard, Yves Borensztein, Silvia Pandolfi, Geoffroy Prévot

Publikováno v: Beilstein Journal of Nanotechnology, Vol 9, Iss 1, Pp 48-56 (2018)

Scanning tunneling microscopy (STM), Auger electron spectroscopy (AES) and low energy electron diffraction have been used to follow the growth of Si films on Ag(111) at various temperatures. Using a simple growth model, we have simulated the distribu

The prediction of silicene [1], a 2D honeycomb crystal of silicon analogous to graphene, lead to intensive theoretical study [2]. Experimental realization has, on the one hand, been successful: although synthesis of free-standing silicene has remaine

Determining the atomic structure of the ( 4×4 ) silicene layer on Ag(111) by combined grazing-incidence x-ray diffraction measurements and first-principles calculations

Autor: Geoffroy Prévot, Yves Borensztein, Alberto Curcella, Andrea Resta, Michele Lazzeri, Romain Bernard

Publikováno v: Physical Review B. 94

From grazing-incidence x-ray diffraction measurements and density functional theory calculations, we have precisely determined the atomic positions of the Si and Ag atoms forming the (4×4) Si/Ag(111) silicene reconstruction. A remarkable agreement i

Silicene multilayers on Ag(111) display a cubic diamondlike structure and a√3×√3reconstruction induced by surfactant Ag atoms

Autor: Sébastien Royer, Alberto Curcella, Yves Borensztein, Geoffroy Prévot

Publikováno v: Physical Review B. 92

The structure of silicene multilayers grown on Ag(111) and the nature of their √3×√3R30◦ reconstruction were studied by low-energy electron diffraction, Auger spectroscopy, and optical reflectance methods. It is shown that the surface reconstr
