Dispersion properties and low infrared optical losses in epitaxial AlN on sapphire substrate in the visible and infrared range

Ali Soltani, Arnaud Stolz, Joël Charrier, Maghnia Mattalah, Jean-Claude Gerbedoen, Hassan Ali Barkad, Vincent Mortet, Michel Rousseau, Nour Eddine Bourzgui, Ali Benmoussa, Jean-Claude de Jaeger

Optical waveguiding properties of a thick wurtzite aluminum nitride highly [002]-textured hetero-epitaxial film on (001) basal plane of sapphire substrate are studied. The physical properties of the film are determined by X-ray diffraction, atomic force microscopy, microRaman, and photocurrent…

Synthesis and electrical characterisations of a low work function cesium oxide coating for high efficiency thermionic energy converter

François Morini, J.F. Robillard, Stéphane Monfray, I.D. Baikie, Thomas Skotnicki, Emmanuel Dubois

One main challenge associated with solid-state thermoelectric materials is to combine electron-crystal electrical conductivity and phonon-glass thermal properties that are difficult to conciliate. A markedly different principle of thermoelectric conversion is based on the micro-thermionic generator…

Silicon pillars as resonators in an acoustical metamaterial

B. Bonello, R. Marchal, R. Moiseyenko, Yan Pennec, Bahram Djafari-Rouhani, J. Zhao, O. Boyko

We have investigated the propagation of Lamb waves in structures made of either an isolated resonant pillar or a set of pillars arranged in a line on a thin plate. The resonators as well as the plate are made of silicon. FEM computations show that two bending modes and one compressional mode are…

Terahertz time-domain spectroscopy of absorbing materials and of metamaterials

Jean-Louis Coutaz, M. Bernier, Frédéric Garet, S. Joly, Y. Miyake, H. Minamide, Eric Lheurette, Didier Lippens

This paper gives a review of recent works we performed in view of characterizing natural materials and metamaterials by terahertz time-domain spectroscopy. We address materials that exhibit a low transmittance in given narrow spectral bands or over the whole experimental spectral window. We give…

200 GHz coherent wireless link using photonics-based emission

Guillaume Ducournau, Y. Yoshimizu, S. Hisatake, F. Pavanello, Emilien Peytavit, Mohammed Zaknoune, T. Nagatsuma, Jean-Francois Lampin

We investigated a coherent THz link at 200 GHz, with variable data rate up to 11 Gbit/s, featuring the combination of a quasi-optic UTC-PD emitter and a high sensitivity electronic receiver. This coherent link relies on an optical frequency comb generator at emission to produce an optical beat note…

Extension of the crosstalk cancellation method in ultrasonic transducer arrays from the harmonic regime to the transient one

Abdelmajid Bybi, Sébastien Grondel, Jamal Assaad, Anne-Christine Hladky

This paper describes a procedure to extend the crosstalk correction method presented in a previous paper [A. Bybi, S. Grondel, J. Assaad, A.–C. Hladky-Hennion, M. Rguiti, Reducing crosstalk in array structures by controlling the excitation voltage of individual elements: a feasibility study,…

Electrolyte-gated organic/nanoparticles synapstor (synapse-transistor) for biocompatible synapse prosthesis

Simon Desbief, Adrica Kyndiah, Mauro Murgia, Tobais Cramer, Fabio Biscarini, David Guérin, Stéphane Lenfant, F. Alibart, Dominique Vuillaume

We have recently demonstrated how we can use charge trapping/detrapping in an array of gold nanoparticules (NPs) at the SiO2/pentacene interface to design a SYNAPSTOR (synapse transistor) mimicking the dynamic plasticity of a biological synapse. This device (memristor-like) mimics short-term…

Magneto-electro-elastic effective properties of multilayered artificial multiferroics with arbitrary lamination direction

Stefano Giordano, Marc Goueygou, Nicolas Tiercelin, Abdelkrim Talbi, Philippe Pernod, Vladimir Preobrazhensky

This work deals with the determination of the effective response of a multilayered or laminated heterostructure composed of materials with an arbitrary coupled anisotropic behavior. In particular, we elaborate a fully algebraic technique for obtaining the homogenized parameters of a magneto-electro…
