Multilayer magnetostrictive structure based surface acoustic wave devices

Huan Zhou, Abdelkrim Talbi, Nicolas Tiercelin, Olivier Bou Matar

This study addresses the experimental and theoretical investigations of guided elastic waves propagation in piezo-magnetic multi-layered structure. The structure is composed of a 20 TbCo2(5nm)/ FeCo(5nm) nanostructured multi-layer deposited between two Aluminum (Al) Inter-Digitals Transducers…

Mercury telluride colloidal quantum dots : electronic structure, size-dependent spectra, and photocurrent detection up to 12 µm

Sean E. Keuleyan, Philippe Guyot-Sionnest, Christophe Delerue, Guy Allan

HgTe colloidal quantum dots are synthesized with high monodispersivity with sizes up to ∼15 nm corresponding to a room temperature absorption edge at ∼5 μm. The shape is tetrahedral for larger sizes and up to five peaks are seen in the absorption spectra with a clear size dependence. The size range…

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…

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…

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…

Digital radio frequency signal generation towards ultimate transmitters

Antoine Frappé

This invited paper exposes our latest developments in the field of digital transmitters by focusing on digital and mixed-signal processing blocks, such as delta-sigma modulators, high-speed interpolation filters and digital-to-RF converters. The goal is to demonstrate that radio-frequency signal…

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…
