Thermal conductivity of deca-nanometric patterned Si membranes by multiscale simulations

Hayat Zaoui, Pier Luca Palla, Stefano Giordano, Fabrizio Cleri, Maxime Verdier, David Lacroix, J.F. Robillard, Konstantinos Termentzidis, Évelyne Martin

The hollowing of silicon membranes to form a lattice of cylindrical holes, also called phononic crystal, has been used by several experimental groups willing to fabricate efficient thermoelectric modules. The idea is to reduce the thermal conductivity without impacting the electronic conductivity.…

Transmission gaps, trapped modes and Fano resonances in Aharonov-Bohm connected mesoscopic loops

T. Mrabti, Z. Labdouti, O. El Abouti, E. H. El Boudouti, F. Fethi, Bahram Djafari-Rouhani

A simple mesoscopic structure consisting of a double symmetric loops coupled by a segment of length do in the presence of an Aharonov-Bohm flux is designed to obtain transmission band gaps and Fano resonances. A general analytical expression for the transmission coefficient and the density of…

Dynamics of the stress-mediated magnetoelectric memory cell N×(TbCo2/FeCo)/PMN-PT

Vladimir Preobrazhensky, Alexey Klimov, Nicolas Tiercelin, Yannick Dusch, Stefano Giordano, Anton Churbanov, Theo Mathurin, Philippe Pernod, Alexander Sigov

Stress-mediated magnetoelectric heterostructures represent a very promising approach for the realization of ultra-low energy Random Access Memories. The magnetoelectric writing of information has been extensively studied in the past, but it was demonstrated only recently that the magnetoelectric…

MIMO in tunnel: impact of polarization and array orientation on the channel characteristics

Frédéric Challita, Pierre Laly, M. Lienard, Davy Gaillot, Pierre Degauque, Jose-Maria Molina-Garcia-Pardo, Wout Joseph

Polarimetric characteristics of the propagation channel in a straight tunnel and in a frequency band around 1.3 GHz, are deduced from measurements using a real-time MIMO channel sounder. Emphasis is on the cross-polarization discrimination factor and, for a MIMO configuration, on the correlation…

Study of the spectral bandwidth of a double-pass acousto-optic system

Justine Champagne, Jean-Claude Kastelik, Samuel Dupont, Joseph Gazalet

Acousto-optic tunable filters are known as efficient instruments for spectral and spatial filtering of light. In this paper, we analyze the bandwidth dependence of a double-pass filter. The interaction geometry chosen allows the simultaneous diffraction of the ordinary and the extraordinary optical…

A fully flexible circuit implementation of clique-based neural networks in 65-nm CMOS

Benoit Larras, Paul Chollet, Cyril Lahuec, Fabrice Seguin, Matthieu Arzel

Clique-based neural networks implement low- complexity functions working with a reduced connectivity be- tween neurons. Thus, they address very specific applications operating with a very low energy budget. This paper proposes a flexible and iterative neural architecture able to implement multiple…

Effect of MoS2 layer on the LSPR in periodic nanostructures

Mohamed El Barghouti, Abdellatif Akjouj, Abdellah Mir

Abstract In this work, we propose a new configuration of the localized surface plasmon resonance (LSPR), based on MoS2 hybrid structures for ultrasensitive biosensing applications. The plasmonic resonances are widely used in bimolecular detection and continue to be an active network because of the…
