Study of Polarisation and Conduction Mechanisms in Ferroelectric Hf0.5Zr0.5O2 Down to Deep Cryogenic Temperature 4.2 K

Benoit Manchon, Dorian Coffineau, Greta Segantini, Nicolas Baboux, Pedro Rojo Romeo, Rabei Barhoumi, Ingrid Cañero Infante, Fabien Alibart, Bertrand Vilquin, Dominique Drouin, Damien Deleruyelle

Two structures, TiN/HZO/TiN and TiN/HZO/AlOx(2nm)/TiN, were fabricated and their electrical properties were studied down to 4.2 K. Low voltage IVs were carried out as well as polarisation-voltage curves at each temperature steps. The aim was to study and compare the evolution of ferroelectric...

Antidictionary-Based Cardiac Arrhythmia Classification

Julien Duforest, Benoit Larras, Deepu John, Olev Märtens, Antoine Frappé

Cardiovascular diseases can be detected early by analyzing the electrocardiogram of a patient using wearable systems. In the context of smart sensors, detecting arrhythmias with good accuracy and ultra-low power consumption is required for long-term monitoring. This paper presents a novel cardiac...

Open-loop cavity flow control with Micro-Magneto-Mechanical Systems (MMMS) microvalves

T. Arnoult, C. Leclercq, Cécile Ghouila-Houri, Romain Viard, Q. Gallas, Eric Garnier, Denis Sipp, A. Merlen, Abdelkrim Talbi, Philippe Pernod

A design of Micro-Magneto-Mechanical microvalves is proposed in this paper to perform open-loop flow control experiments on an open-cavity flow. The unstable flow developing over the open cavity is sensitive to the velocity fluctuations induced by a forcing. Consequently, a linear array of...

SOI-based micro-mechanical terahertz detector operating at room-temperature and atmospheric pressure

Kevin Froberger, Benjamin Walter, Melanie Lavancier, Romain Peretti, Guillaume Ducournau, Jean-Francois Lampin, Marc Faucher, Stefano Barbieri

We present a micro-mechanical terahertz (THz) detector fabricated on a silicon on insulator substrate and operating at room-temperature. The device is based on a U-shaped cantilever of micrometric size, on top of which two aluminum half-wave dipole antennas are deposited. This produces an...

Distributed Artificial Intelligence Integrated Circuits For Ultra-Low-Power Smart Sensors

Mathieu Chêne, Benoit Larras, Antoine Frappé, Andreas Kaiser

Wireless sensor networks (WSN) could be defined as networks of autonomous devices that can sense and/or act on a physical or environmental conditions cooperatively. .To make these sensors smarter, Artificial Intelligence (AI) is used to process sensed data but also to solve challenges such as...

Preserving the Minimum Distance of Polar-Like Codes while Increasing the Information Length

Samet Gelincik, Philippe Mary, Anne Savard, Jean-Yves Baudais

Reed Muller (RM) codes are known for their good minimum distance. One can use their structure to construct polar-like codes with good distance properties by choosing the information set as the rows of the polarization matrix with the highest Hamming weight, instead of the most reliable synthetic...

Modeling and simulation of GaAsPN / GaP quantum dot structure for solar cell in intermediate band solar cell applications

Abdelkader Aissat, Lynda Chenini, Said Nacer, Jean-Pierre Vilcot

This effort is founded on the modeling and simulation of the GaAsPN/GaP quantum dot (QD) solar cell. This quaternary alloy is one of the III-V semiconductors, which gained importance in the recent years for optoelectronic applications. This importance comes from the fact that the quaternary GaAsPN...

Wideband mm-Wave Integrated Passive Tuners for Accurate Characterization of BiCMOS Technologies

Marc Margalef-Rovira, Caroline Maye, Sylvie Lepilliet, Daniel Gloria, Guillaume Ducournau, Christophe Gaquière

This paper presents an innovative impedance tuner architecture aiming at on-wafer characterization. The proposed impedance tuner is composed of an integrated attenuator, which can be tuned in an analog manner, and a transmission line. Thanks to the use of an external short-circuited probe, the...

Thermally Conductive and Leakage-Proof Phase-Change Materials Composed of Dense Graphene Foam and Paraffin for Thermal Management

Hongling Li, Roland Yingjie Tay, Siu Hon Tsang, Romain Hubert, Philippe Coquet, Thomas Merlet, Jerome Foncin, Jong Jen Yu, Edwin Hang Tong Teo

Practical implementation of porous carbon-based composite phase-change materials (CPCMs) for heat dissipation in high-power-density electronics is usually limited by liquid leakage issues and unsatisfactory thermal conductivity resulting from their relatively low filler fraction and/or existence of...
