On-wafer differential noise figure measurement without couplers on a vector network analyzer

Yogadissen Andee, Alexandre Siligaris, Francois Graux, Francois Danneville

This papers presents a measurement technique for the noise figure of on-wafer differential amplifiers using 4-port network analyzers. The approach is based on the determination of the correlation of output noise waves in terms of the 4-port S-parameters and of the output noise powers. The…

Finite element analysis and experimental study of surface acoustic wave propagation through two-dimensional pillar-based surface phononic crystal

S. Yankin, Abdelkrim Talbi, Y. Du, Jean-Claude Gerbedoen, Vladimir Preobrazhensky, Philippe Pernod, Olivier Bou Matar

We study both theoretically and experimentally the interaction of surface elastic waves with 2D surface phononic crystal (PnC) on a piezoelectric substrate. A rigorous analysis based on 3D finite element method is conducted to calculate the band structure of the PnC and to analyze the transmission…

Synthesis and electrical conductivity of multilayer silicene

Patrick Vogt, Pierre Capiod, Maxime Berthe, Andrea Resta, Paola de Padova, Thomas Brühne, Guy Le Lay, B. Grandidier

The epitaxial growth and the electrical resistance of multilayer silicene on the Ag(111) surface has been investigated. We show that the atomic structure of the first silicene layer differs from the next layers and that the adsorption of Si induces the formation of extended silicene terraces…

High performance TiN gate contact on AlGaN/GaN transistor using a mechanically strain induced P-doping

Ali Soltani, Michel Rousseau, Jean-Claude Gerbedoen, Maghnia Mattalah, P.L. Bonanno, A. Telia, Nour Eddine Bourzgui, Gilles Patriarche, A. Ougazzaden, A. Ben Moussa

High performance titanium nitride sub-100 nm rectifying contact, deposited by sputtering on AlGaN/GaN high electron mobility transistors, shows a reverse leakage current as low as 38 pA/mm at VGS = -40 V and a Schottky barrier height of 0.95 eV. Based on structural characterization and 3D…

Narrow linewidth generation at 1 THz using cascaded Brillouin fiber lasers and quasi-optic UTC-PD

Guillaume Ducournau, Denis Bacquet, P. Szriftgiser, Fabio Pavanello, Emilien Peytavit, Mohammed Zaknoune, Alexandre Beck, Jean-Francois Lampin

Narrow linewidth THz generation using a cascaded Brillouin fibre laser structure and a unitraveling carrier photodiode is proposed. Using two distributed feedback lasers separated by > 1 THz with 1 MHz initial linewidth, the linewidth of the realized THz source is found to be < 100 Hz at 1014…

Transition de phase et propriétés diélectriques de films de Ba(0.3)Sr(0.7)TiO3 déposés sur Al2O3 avec une couche tampon de TiO2

Areski Ghalem, Freddy Ponchel, Denis Remiens, Tuami Lasri

Dans cet article, nous proposons l'étude des propriétés diélectriques ainsi que l'évolution de la transition de phase des films de Ba(0.3)Sr(0.7)TiO3 déposés par pulvérisation cathodique sur un substrat de saphir muni d'une couche tampon de TiO2 afin de contrôler l'orientation…

Broadband sound shielding of Lamb waves through a periodic array of junctions

R.P. Moiseyenko, Yan Pennec, R. Marchal, B. Bonello, Bahram Djafari-Rouhani

We study theoretically sub-wavelength physical phenomena such as resonant transmission and broadband sound shielding for Lamb waves propagating in an acoustic metamaterial made of a thin plate drilled with one or two row(s) of rectangular holes. One of the main results is the demonstration of a…
