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…

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…

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…
