Homo-epitaxial growth of LiNbO3 thin films by Pulsed Laser deposition

Laura Sauze, Nicolas Vaxelaire, Roselyne Templier, Denis Rouchon, François Pierre, Cyril Guedj, Denis Remiens, Guillaume Rodriguez, Marie Bousquet, Florian Dupont

With the deployment of the 5th Generation of mobile applications (5G), the performances of radio-frequency (RF) filters are pushed to their limits. Highly crystalline piezoelectric materials with an electromechanical coupling coefficient higher than aluminium nitride are of high interest. Lithium…

THz topological Waveguides in 600 GHz frequency Region

Abdu Subahan Mohamed, Edouard Lebouvier, Gaëtan Lévêque, Yan Pennec, Marc Faucher, Alberto Amo, Pascal Szriftgiser, Guillaume Ducournau

We experimentally demonstrate a silicon-based valley photonic crystal (VPC) waveguide for the 590-620 GHz frequency region. We specifically conduct measurements on the transmission and group delay for normal silicon waveguides and Valley photonic crystal waveguides and state that topological valley…

Fabrication of silicon nitride membrane nanoelectromechanical resonator

Hao Xu, Srisaran Venkatachalam, Christophe Boyaval, Pascal Tilmant, Francois Vaurette, Yves Deblock, Didier Theron, Xin Zhou

In this work, we present details of the nanofabrication process for achieving a silicon nitride nanoelectromechanical resonator, consisting of a membrane covered with a thin aluminium layer capacitively coupled to a suspended top gate. Critical nanofabrication steps have been discussed, including…

Metal-based folded-thermopile for 2.5D micro-thermoelectric generators

Ibrahim Bel-Hadj, Zahia Bougrioua, Katir Ziouche

We report on the simulation and fabrication of 2.5D micro-thermoelectric generators (µTEGs) with a thermopile topology periodically folded and distributed on a multi-membrane template, capable of harvesting lost heat directly into useful electrical energy. The originality of the folded thermopile…

On exploiting the synaptic interaction properties to obtain frequency-specific neurons

Guillaume Marthe, Claire Goursaud, Romain Cazé, Laurent Clavier

Energy consumption remains the main limiting factors in many IoT applications. In particular, micro-controllers consume far too much power. In order to overcome this problem, new circuit designs have been proposed and the use of spiking neurons and analog computing has emerged as it allows a very…

Robust Al0.23Ga0.77N channel HFETs on bulk AlN for high voltage power electronics

J. Mehta, Idriss Abid, Reda Elwaradi, Yvon Cordier, F Medjdoub

AlxGa1-xN heterojunction FETs (HFETs) have been an eye catcher for high voltage power electronics with its potential to outperform the predecessors by virtue of high critical breakdown field of the material, which can be tuned by varying Al mole-fraction. In this work, we demonstrate Al0.23Ga0.77N…
