Waves in periodic media : Fourier analysis shortcuts and physical insights, case of 2D phononic crystals

Samuel Dupont, Joseph Gazalet, Jean-Claude Kastelik

Phononic crystal is a structured media with periodic modulation of its physical properties that influences the propagation of elastic waves and leads to a peculiar behaviour, for instance the phononic band gap effect by which elastic waves cannot propagate in certain frequency ranges. The…

On wafer silicon integrated noise source characterization up to 110 GHz based on germanium-on-silicon photodiode

Sandrine Oeuvrard, Jean-Francois Lampin, Guillaume Ducournau, Sylvie Lepilliet, Francois Danneville, Thomas Quemerais, Daniel Gloria

In this work, a new concept of photonic noise source has been developed and characterized, based on Germanium-on-Silicon high speed photodiode (GeHSPD). This photodiode RF output power has been preliminary characterized up to 210 GHz, using a dedicated optoelectronic bench and demonstrating…

Enhancing LSPR sensitivity of Au gratings through graphene coupling to Au film

Thomas Maurer, Rana Nicolas, 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

A particular interesting plasmonic system is that of metallic nanostructures interacting with metal films. As the localized surface plasmon resonance (LSPR) behavior of gold nanostructures (Au NPs) on the top of a gold thin film is exquisitely sensitive to the spacer distance of the film-Au NPs, we…

1 to 220 GHz complex permittivity behavior of flexible polydimethylsiloxane substrate

Pierre-Yves Cresson, Yovan Orlic, Jean-François Legier, Erick Paleczny, Luc Dubois, Nicolas Tiercelin, Philippe Coquet, Philippe Pernod, Tuami Lasri

Coplanar transmission lines (CPW) are realized on polydimethylsiloxane (PDMS) substrate in order to characterize its complex permittivity, from 1 to 220 GHz. By varying the complex permittivity, the propagation constant of the PDMS-CPW calculated with full wave software is matched to those…

Etude de l'influence de la pointe sur les mesures KFM sur échantillon d'AlGaAs/GaAs

Sylvain Pouch, Nicolas Chevalier, Denis Mariolle, François Triozon, Thierry Melin, Lukasz Borowik

La microscopie à sonde de Kelvin (KFM) est capable de fournir une mesure résolue spatialement et en énergie de la structure de bande en surface d'un matériau. Elle dépend néanmoins fortement des propriétés physiques de la pointe utilisée, propriétés pouvant être la largeur de l'apex, la…

Elastic properties of tensile nitrogen-plasma-treated multilayer silicon nitride films

M. Braccini, F. Volpi, Arnaud Devos, G. Raymond, D. Benoit, Pascal Morin

Highly stressed silicon nitride thin films are used in gate first complementary metal oxide semiconductors to improve mobility in the silicon channel. Compressive stresses improve hole mobility in p-type MOS transistors while tensile stresses increase electron mobility in n-type MOS devices. High…
