From Low Symmetry to High Dissymmetry: Chiral Plasmonic Films of Binary and Nanobipyramid Assemblies

open access: yesAdvanced Functional Materials, EarlyView.
This work develops highly dissymmetric chiral plasmonic thin films by helically assembling gold nano bipyramids within a liquid‐crystal template. Engineering of the chiroptical response is achieved by varying particle size and geometry, as well as preparing binary assemblies.

Surface Plasmon Polariton Graphene Photodetectors. [PDF]

open access: yesNano letters (Print), 2015
The combination of plasmonic nanoparticles and graphene enhances the responsivity and spectral selectivity of graphene-based photodetectors. However, the small area of the metal-graphene junction, where the induced electron-hole pairs separate, limits ...

SURFACE PLASMONS ON A RANDOMLY ROUGH SURFACE

open access: yesLe Journal de Physique Colloques, 1983
We have studied the dispersion relation for surface plasmons on a randomly rough surface, going beyond the lowest approximation in the surface profile function. The expansion of the surface plasmon dispersion relation in powers of the surface profile function contains an infinite subset of terms that are all of the same order of magnitude as the lowest
