Nanometal plasmon polaritons

Abdellatif Akjouj, Gaëtan Lévêque, Sabine Szunerits, Yan Pennec, Bahram Djafari-Rouhani, Rabah Boukherroub, L. Dobrzynski

A nanometal is a nanometric metallic structure. A plasmon is a collective excitation of an electron gas. A plasmon polariton is a plasmon coupled to an electromagnetic wave. Whereas plasmons in bulk metal do not couple to light fields, a thin metal film can sustain surface polaritons when excited...

Enhanced gold film-coupled graphene-based plasmonic nanosensor

Rana Nicolas, Thomas Maurer, Gaëtan Lévêque, P. Subramanian, Julien Proust, Jérémie Béal, Silvere Schuermans, Jean-Pierre Vilcot, Z. Herro, M. Kazan, Jerome Plain, Rabah Boukherroub, Abdellatif Akjouj, Bahram Djafari-Rouhani, Pierre-Michel Adam, Sabine Szunerits

In this work, a trilayer graphene is used as a thin non dielectric spacer with a high index of refraction, between Au film and Au NPs. Encouraged by the sharpness of the localized surface plasmon resonance LSPR induced by this system, we performed sensitivity measurements to refractive index change...

Scanning Gate Spectroscopy of transport across a Quantum Hall Nano-Island

F. Martins, S. Faniel, B. Rosenow, M. G. Pala, Hermann Sellier, Serge Huant, L. Desplanque, X. Wallart, Vincent Bayot, B. Hackens

We explore transport across an ultra-small Quantum Hall Island (QHI) formed by closed quan- tum Hall edge states and connected to propagating edge channels through tunnel barriers. Scanning gate microscopy and scanning gate spectroscopy are used to first localize and then study a single QHI near a...

Ultrafast short-range disordering of femtosecond-laser-heated warm dense aluminum

P. M. Leguay, A. Levy, B. Chimier, F. Deneuville, D. Descamps, C. Fourment, C. Goyon, S. Hulin, S. Petit, O. Peyrusse, J. J. Santos, P. Combis, B. Holst, V. Recoules, P. Renaudin, L. Videau, F. Dorchies

We have probed, with time-resolved x-ray absorption near-edge spectroscopy (XANES), a femtosecond-laser-heated aluminum foil with fluences up to 1 J/cm2. The spectra reveal a loss of the short-range order in a few picoseconds. This time scale is compared with the electron-ion equilibration time,...
