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...

Ferroelectric thin films working at microwave frequency for reconfigurable devices on silicon substrate: performances comparison between BST, PST

Freddy Ponchel, Denis Remiens, Areski Ghalem, Tuami Lasri

The dielectric microwave performance of BST and PST films is studied via tunability. The films are deposited onto silicon wafer with high resistivity using radio frequency magnetron sputtering with an in situ process for BST films and ex situ for PST films. In order to improve the crystalline...

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...

Modeling and simulation of AlxGayIn1-x-yAs/InP quaternary structure for photovoltaic

Abdelkader Aissat, M. El Bey, Rachid Bestam, Jean-Pierre Vilcot

In this work, we have studied solar cells based on AlGaInAs/InP quaternary structure to describe the behavior of electronics components. To this end, we have developed a simulation program to study the gallium Ga and aluminum Al concentrations effect on respectively the lattice mismatch, the band...

Guided wave in multilayered piezoelectric-piezomagnetic bars with rectangular cross-sections

J.G. Yu, Jean-Etienne Lefebvre, C. Zhang

For the purpose of design and optimization of multilayered piezoelectric-piezomagnetic material (PPC) transducers, wave propagation in these structures has received much attention in past ten years. But the research objects of previous works are only for semi-infinite structures and one-dimensional...

Insulin loaded iron magnetic nanoparticle–graphene oxide composites: synthesis, characterization and application for in vivo delivery of insulin

Kostiantyn Turcheniuk, Manakamana Khanal, Anastasiia Motorina, Palaniappan Subramanian, Alexandre Barras, Vladimir Zaitsev, Victor Kuncser, Aurel Leca, Alain Martoriati, Katia Cailliau-Maggio, Jean-Francois Bodart, Rabah Boukherroub, Sabine Szunerits

One of the focal subjects in insulin delivery is the development of insulin formulations that protect the native insulin from degradation under acidic pH in the stomach. In this work we show, for the first time, that a graphene oxide (GO) based matrix can ensure the stability of insulin at low pH....

Band gap formation and elastic wave transmission in two-dimentional surface phononic crystal

Sergey Yankin, Abdelkrim Talbi, Yu Du, Jean-Claude Gerbedoen, Vladimir Preobrazhensky, Philippe Pernod, Olivier Bou Matar

Using finite element method analysis of surface acoustic wave (SAW) propagation in the phononic crystal in a form of periodic lattice from nickel pillars, located on a piezoelectric substrate of Y+128°-cut LiNbO3, has been conducted. Amplitude and phase characteristics of SAW propagation through...
