Double-pentagon silicon chains in a quasi-1D Si/Ag(001) surface alloy
Autor: Conor Hogan, Andrea Sette, Vasil A. Saroka, Stefano Colonna, Roberto Flammini, Laurita Florean, Romain Bernard, Laurence Masson, Geoffroy Prévot, Fabio Ronci
Publikováno v: Nature Communications, Vol 15, Iss 1, Pp 1-10 (2024)
Abstract Silicon surface alloys and silicide nanolayers are highly important as contact materials in integrated circuit devices. Here we demonstrate that the submonolayer Si/Ag(001) surface reconstruction, reported to exhibit interesting topological

Chiral Excitation of Exchange Spin Waves Using Gold Nanowire Grating
Autor: Loic Temdie, Vincent Castel, Timmy Reimann, Morris Lindner, Carsten Dubs, Gyandeep Pradhan, Jose Solano, Romain Bernard, Hicham Majjad, Yves Henry, Matthieu Bailleul, Vincent Vlaminck
Publikováno v: Magnetochemistry, Vol 9, Iss 8, p 199 (2023)
We propose an experimental method for the unidirectional excitation of spin waves. By structuring Au nanowire arrays within a coplanar waveguide onto a thin yttrium iron garnet (YIG) film, we observe a chiral coupling between the excitation field geo

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

Publikováno v: Molecules, Vol 27, Iss 1, p 62 (2021)
Surface enhanced infrared absorption spectroscopic studies (SEIRAS) as a technique to study biological molecules in extremely low concentrations is greatly evolving. In order to use the technique for identification of the structure and interactions o

Resolving the structure of the striped Ge layer on Ag(111):Ag2Ge surface alloy with alternate fcc and hcp domains
Autor: Bruno Grandidier, I. Lefebvre, Yves Borensztein, K. Zhang, M. Derivaz, P. Diener, Geoffroy Prévot, Davide Sciacca, Alessandro Coati, C. Pirri, Romain Bernard
Publikováno v: Physical Review B. 104
Two-dimensional (2D) honeycomb lattices beyond graphene, such as germanene, promise new physical properties such as quantum spin Hall effect. While there have been many claims of growth of germanene, the lack of precise structural characterization of
