Thin-film adhesion characterization by Colored Picosecond Acoustics

Arnaud Devos, P. Emery

This paper presents some applications of a recent technique so-called the Colored Picosecond Acoustics (APiC) to the characterization of complex stacks of thin films. The technique is a unique combination of optics and acoustics that implements an acoustic pulse-echo technique at the nanoscale...

Magnonic analogue of electromagnetic induced transparency in detuned magnetic circuit

Abdelkader Mouadili, El Houssaine El Boudouti, Housni Al-Wahsh, Abdellatif Akjouj, Bahram Djafari-Rouhani, L. Dobrzynski

A simple magnetic device consisting of two dangling side stubs grafted at the same site along a waveguide is designed to obtain a magnonic analogue of electromagnetic induced transparency (EIT) resonance. By detuning the lengths of the two stubs, a resonance can be squeezed between two transmission...

On the two-way diamond relay channel with lattice-based Compress-and-Forward

Anne Savard, Laurent Clavier

This paper focuses on the full-duplex Gaussian two-way diamond relay channel (TWDRC), where two users wish to exchange their messages with the help of two relays, when one relay performs a lattice-based Compress-and-Forward (CF) scheme. The other relay performs either Decode-and-Forward (DF),...

A broadband 4-18 GHz active quadrature hybrid

Paul Sangare, Christophe Loyez, Kevin Carpentier, Markus Mayer, Dirk Hartung, Francois Parickmiler, Nathalie Rolland

This paper presents an innovative topology of a broadband active quadrature hybrid. This novel architecture consists of a traveling wave amplifier with a unique coupling mechanism, providing amplitude flatness and low phase imbalance over the 4 - 18 GHz frequency band. Experimental results validate...

Toward a better understanding of the doping mechanism involved in Mo(tfd-COCF3)(3) doped PBDTTT-c

J. Euvrard, A. Revaux, S. S. Nobre, A. Kahn, Dominique Vuillaume

In this study, we aim to improve our understanding of the doping mechanism involved in the polymer poly[(4,8-bis-(2-ethylhexyloxy)-benzo(1,2-b:4,5-b')dithiophene)-2,6-diyl-alt-(4-(2-ethylhexanoyl)-thieno[3,4-b]thiophene-)-2-6-diyl)] (PBDTTT-c) doped with tris[1-(trifluoroethanoyl)-2-(...

Controlled modiﬁcation of electrochemical microsystems with polyethylenimine/reduced graphene oxide using electrophoretic deposition: Sensing of dopamine levels in meat samples

Karima Kahlouche, Roxana Jijie, Ioana Hosu, Alexandre Barras, Reda Yahiaoui, Tijani Gharbi, Guillaume Herlem, Ferhat Marhoun, Sabine Szunerits, Rabah Boukherroub

Microsystems play an important role in many biological and environmental applications. The integration of electrical interfaces into such miniaturized systems provides new opportunities for electrochemical sensing where high sensitivity and selectivity towards the analyte are requested. This can be...

Non-destructive characterization of surfaces and thin coatings using a large-bandwidth interdigital transducer

Dame Fall, Marc Duquennoy, Mohammadi Ouaftouh, Nikolay Smagin, Bogdan Piwakowski, Frédéric Jenot

This paper deals with non-destructive testing of thin layer structures using Rayleigh-type waves over a broad frequency range (25-125 MHz). The dispersion phenomenon was used to characterize a layer-on-substrate-type sample comprising a thin layer of platinum 100 nm thick on a silicon substrate....

Chapter 4 - One-dimensional phononic crystals

El Houssaine El Boudouti, Abdellatif Akjouj, L. Dobrzynski, Bahram Djafari-Rouhani, Yan Pennec, Housni Al-Wahsh, Gaëtan Lévêque

In this chapter we study the band gap structures as well as the effect of inhomogeneities within the perfect one-dimensional (1D) phononic crystal (PnC) such as a free surface, a PnC/substrate interface, and a defect layer embedded in these systems. Such inhomogeneities are usually present in...

Cation discrimination in organic electrochemical transistors by dual frequency sensing

Sébastien Pecqueur, Dominique Vuillaume, David Guérin, F. Alibart

In this work, we propose a strategy to sense quantitatively and specifically cations, out of a single organic electrochemical transistor (OECT) device exposed to an electrolyte. From the systematic study of six different chloride salts over 12 different concentrations, we demonstrate that the...
