Back-gated microwave field-effect transistors based on transferred CVD-grown graphene

Wei Wei, Mohamed Moez Belhaj, Geetanjali Deokar, D. Mele, Emiliano Pallecchi, Emmanuelle Pichonat, Dominique Vignaud, Henri Happy

Graphene based transistors have drawn growing interest from both industries and Laboratories [1-3]. In this work, we present both fabrication process and characterization of graphene field-effect transistors. Large scale monolayer graphene was grown by chemical vapor deposition (CVD) on Cu foils…

Surface acoustic wave bandgaps for conical pillars on a piezoelectric substrate

Abdelali Mrabti, Mourad Oudich, Abdellatif Akjouj, Yan Pennec, Bahram Djafari-Rouhani, Abdelkrim Talbi, Jérémy Streque, Yu Du, Ali Soltani, Philippe Pernod

We report theoretically on the band structure of a square lattice phononic crystal made up of nickel (Ni) conical pillars deposited on the surface of a semi-infinite LiNbO3 substrate. Calculations have been performed with a 3D finite element method taking into account material anisotropy and…

Wave propagation in layered piezoelectric rectangular bar : an extended orthogonal polynomial approach

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

Wave propagation in multilayered piezoelectric structures has received much attention in past forty years. But the research objects of previous research works are only for semi-infinite structures and one-dimensional structures, i.e., structures with a finite dimension in only one direction, such…

Noise performance of frequency modulation Kelvin force microscopy

Heinrich Diesinger, D. Deresmes, Thierry Melin

Noise performance of a phase-locked loop (PLL) based frequency modulation Kelvin force microscope (FM-KFM) is assessed. Noise propagation is modeled step by step throughout the setup using both exact closed loop noise gains and an approximation known as "noise gain" from operational…

High polarization high breakdown voltage AlN/GaN-on-silicon transistors

Nicolas Herbecq, Isabelle Roch-Jeune, F Medjdoub

We have developed a back-side process on AlN/GaN-on-Si DHFETs in order to drastically enhance their electrical performances. With a buffer thickness of 1.8 μm, the Si substrate has been locally etched up to the buffer layers between the drain and the gate. After local silicon removal, the three-…

Fabrication of magnetoelastic Bragg reflectors for surface acoustic wave applications and investigation of its tuning with constant magnetic field

Anastasia Pavlova, Sergey Yankin, Abdelkrim Talbi, Jean-Claude Gerbedoen

In this work studying of 1D periodic phononic crystal (PnC) fabrication for 2 GHz and 4 GHz on Ni was done experimentally and theoretically using finite element analysis (FEA). Change of crystal acoustic properties in applied magnetic field was evaluated theoretically.

Fabrication and characterization of 2D phononic crystals based on lithium niobate substrate and nickel pillars

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

This work presents experimental investigation of interaction between surface acoustic waves and 2D surface Phononic crystals (PnCs). The PnC is made of 2D array of resonant nickel pillars arranged in different symmetric lattices, and deposited on lithium niobate (Y128 cut) substrate. Measurement of…

Impact du recuit d'activation sur la passivation par Al2O3 du silicium type p Cz

Matthieu Pawlik, Jean-Pierre Vilcot, Mathieu Halbwax, M. Gauthier, N. Le Quang

L'Al2O3 déposé par ALD est un diélectrique bien connu pour la passivation de surface du silicium type-p. Cependant, une étape de recuit post-dépôt est nécessaire pour activer la passivation. Grâce à des mesures de densités de charges effectives, de défauts d'interface, temps de vie de…

Sensing light and sound velocities of fluids in 2D phoxonic crystal slab

Yan Pennec, R. Moiseyenko, Bahram Djafari-Rouhani, S. Amoudache, R. Tigrine, R. Lucklum, A. Khater

We study theoretically the potentiality of dual phononic-photonic (the so-called phoxonic) crystals for sensing applications. In this work, we study the transmission normal to a periodically perforated silicon slab when the surrounding medium is a liquid. We investigate the existence of well-…
