Contact resistance study of “edge-contacted” metal-graphene interfaces

V. Passi, A. Gahoi, J. Ruhkopf, S. Kataria, Francois Vaurette, E. Pallecchi, H. Happy, M. C. Lemme

The contact resistance RC of "edge-contacted" metal-graphene interfaces is systematically studied. Our experiments demonstrate a reduction of contact resistance by intentional patterning of graphene to create "edge contacts". The parameter space for different hole patterns in…

Deep Trench Isolation and Through Silicon Via Wetting Characterization by High-Frequency Acoustic Reflectometry

Christophe Virgilio, Lucile Broussous, Philippe Garnier, Julien Carlier, Pierre Campistron, V. Thomy, Malika Toubal, Pascal Besson, Laurence Gabette, Bertrand Nongaillard

Wetting efficiency of microstructures or nanostructures patterned on Si wafers is a real concern in integrated circuits manufacturing. We present here a high-frequency acoustic method which enables the local determination of the wetting state of a liquid on real DTI and TSV structures. Partial…

Development of a patch antenna based on a Polyaniline/Carbon coated Cobalt composite

Z. Hamouda, J.-L. Wojkiewicz, A.A. Pud, Lamine Kone, C. Hamouda, S. Bergheul, T. Lasri

In this study, a patch antenna including a thick film made of a composite material based on Polyaniline (PANI) and Carbon coated Cobalt (CCo) is investigated. Conception, simulation, realization and characterization steps are presented. The morphology of the obtained composite was studied via…

Electronic structure investigation of Al0.7Ga0.3As/GaAs nanometric heterostructures by Kelvin force microscopy

Sylvain Pouch, Francois Triozon, Nicolas Chevalier, Thierry Melin, Yann Michel Niquet, Lukasz Borowik

Kelvin force microscopy provides a spatially resolved measurement of the surface potential, which is related to the energetic band structure of a material. The goal of this work is to investigate the surface potential on Al0.7Ga0.3As and GaAs heterostructures with a decreasing layer thickness up to…

Magnetic-Phase Dependence of the Spin Carrier Mean Free Path in Graphene Nanoribbons

Jing Li, Yann-Michel Niquet, Christophe Delerue

We show theoretically that the intrinsic (phonon-limited) carrier mobility in graphene nanoribbons is considerably influenced by the presence of spin-polarized edge states. When the coupling between opposite edges switches from antiferromagnetic to ferromagnetic with increasing carrier density, the…

Containment nuclear plant structures evaluation by non destructive testing: strategy and results

Vincent Garnier, Jean-Marie Henault, Hamid Hafid, Jérôme Verdier, Jean François Chaix, Odile Abraham, Zoubir Medhi Sbartaï, Jean-Paul Balayssac, Bogdan Piwakowski, Géraldine Villain, Xavier Derobert, Cédric Payan, Sandrine Rakotonarivo, Éric Larose, Hognon Sogbossi, Quang Anh Vu, Martin Lott, Jean-Baptiste Legland, Olivier Durand, Radoslaw Drelich, Charles Ciccarone

Containment nuclear plants structures are an ultimate barrier in the event of an accident. Mechanical resistance and tightness are the two functions that they are expected to provide. To evaluate their capacity to perform them, destructive testing cannot be used to characterize the material. Non-…

METASTABILITY OF FINITE STATE MARKOV CHAINS: A RECURSIVE PROCEDURE TO IDENTIFY SLOW VARIABLES FOR MODEL REDUCTION

Claudio Landim, T. Xu

Consider a sequence (η N (t) : t ≥ 0) of continuous-time, irreducible Markov chains evolving on a fixed finite set E. Denote by R N (η, ξ) the jump rates of the Markov chain η N t , and assume that for any pair of bonds (η, ξ),

DS-UWB and TH-UWB Energy Consumption Comparison

Adil Elabboubi, Fouzia Elbahhar, Marc Heddebaut, Yassin El Hillali

The energy consumption of the wireless communication systems is starting to be unaffordable. One way to improve the power consumption is the optimization of the communication techniques used by the communication networks and devices. In order to develop an energy efficient UWB multi-user…
