Structure of germanene/Al(111): a two-layers surface alloy
K. Zhang, D. Sciacca, M. -C. Hanf +12
Unlike silicene, for which the demonstration of its existence has been done through numerous independent studies, the possibility of growing epitaxial germanene remains highly cont…
Resolving the structure of the striped Ge layer on Ag(111): AgGe surface alloy with alternate fcc and hcp domains
K. Zhang, D. Sciacca, A. Coati +8
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 g…
Gas-induced selective re-orientation of Au-Cu nanoparticles on TiO 2 (110)
Axel Wilson, Aude Bailly, Romain Bernard +11
Au-Cu bimetallic nanoparticles (NPs) grown on TiO 2 (110) have been followed in-situ using grazing incidence x-ray diffraction and x-ray photoemission spectroscopy from their synth…
Growth of germanium-silver surface alloys followed by in situ scanning tunneling microscopy: Absence of germanene formation
Kai Zhang, Romain Bernard, Yves Borensztein +2
Theoretical studies have shown that new physical properties such as tunable gap openings or quantum spinHall effects could be expected from group-IV graphene analogs (silicene, ger…
Ultrasensitive and fast single wavelength plasmonic hydrogen sensing with anisotropic nanostructured Pd films
William L. Watkins, Yves Borensztein
Anisotropic nanostructured porous Pd films are fabricated using oblique angle deposition in vacuum on a glass substrate. They display a dichroic response, due to localised surface…
Mechanism of hydrogen adsorption on gold nanoparticles and charge transfer probed by anisotropic surface plasmon resonance
William L. Watkins, Yves Borensztein
The adsorption of hydrogen on Au nanoparticles (NPs) of size of the order of 10 nm has been investigated by use of localised surface plasmon resonances (LSPR) in the NPs. The sampl…
