Band structure tuning at (La,Sr)MnO3 / (Ba,Sr)TiO3 interface

Jérôme Wolfman, Antoine Ruyter, B. Negulescu, Pascal Andreazza, Xavier Wallart, Sylvie Schamm-Chardon, Robin Cours, Teresa Hungria, Cecile Autret

Band structure engineering in silicon-based heterostructures dedicated to microelectronic and energy harvesting applications has been common material scientist playground for decades. Careful design of the energy level variation at hetero-interfaces is used e.g. to collect electron while preventing…

100 Gbit/s THz Data Transmission and Beyond using Multicore Fiber Combined with UTC Photodiode Array

Alfred Bewindin Sawadogo, Aritrio Bandyopadhyay, Malek Zegaoui, Mohammed Zaknoune, P. Szriftgiser, Karen Baudelle, Monika Bouet, Géraud Bouwmans, Davy Gaillot, Esben Ravn Andresen, Guillaume Ducournau, Laurent Bigot

Photonics-driven transmitters are leading the race towards high data-rates at THz frequencies. Here, spatial-multiplexing based on multicore fiber and photodiodes array is considered to alleviate the limited output power. Sub-systems have been developed and validated.

Blockchain-Based Collaborative Certificate Revocation Systems Using Clustering

Ahmed Didouh, Houda Labiod, Yassin El Hillali, Atika Rivenq

Despite the decisive contribution of intelligent transport systems in road safety, they also open new vulnerabilities to cyber-attacks, particularly vehicle position-linked attacks. For that reason, centralized systems are becoming increasingly vulnerable to the growth of the connected-vehicle…

The good, the bad and the ugly polishing: Effect of abrasive size on standardless EDS analysis of Portland cement clinker’s calcium silicates

Vincent Thiéry, Emmanuel Dubois, Séverine Bellayer

Standardless Energy dispersive spectroscopy (EDS) on polished samples of Portland cement clinker is routinely performed both for unhydrated phases as well as in cement pastes. Typically, the calcium to silica ratio is investigated. EDS analyses are highly dependent on the polishing quality of the…

Switchability of a single port SAW resonator using the electrical Bragg band gap

R. Alcorta Galván, Charles Croënne, Bertrand Dubus, B. Loiseaux, E. Eustache, M. Bertrand, Anne-Christine Hladky

A proof of concept of a new solution for achieving tunable SAW components based on the electrical Bragg band gap concept developed for piezoelectric phononic crystals is presented on a SAW resonator on a LiNbO3 substrate. In this work, it is shown that for a fixed geometry, it is possible to shift…

Towards highly efficient high power X‐band AlN/GaN MIS HEMTs operating above 50V

Kathia Harrouche, Sri Saran Vankatachalam, François Grandpierron, Etienne Okada, F Medjdoub

We report on AlN/GaN MISHEMT technology on SiC substrate for X-band applications. Transistors with 100 nm gate lengths deliver a high off-state breakdown voltage above 180V and 110 V in semi-on state. RF small signal measurements up to a drain bias (VDS) as high as 70V for two different gate…

Modeling of access resistances and channel temperature estimation for GaN HEMT

Shariful Islam, Mohammad Abdul Alim, Abu Zahed Chowdhury, Christophe Gaquière

Accurate prediction of resistances at the transistor’s access zone and their temperature dependency are very important, since the current flow to the device depends on that region. In this paper, we have modeled the access resistances and have verified their temperature dependency with the…

Electro-Acoustic Properties of Scandium-Doped Aluminum Nitride (Sc_xAl_1-xN) Material and its Application to Phononic Crystal-Coupled SAW Devices

Fahima Arab, Fares Kanouni, Rafik Serhane, Yan Pennec, Zafer Özer, Khaled Bouamama

Within the framework of the Density Functional Theory, the elastic, dielectric, and piezoelectric coefficients of w-ScxAl1−xN material were investigated for scandium (Sc) concentrations x = 0 to 0.375. The electro-acoustic properties are used to investigate the frequency response of the SAW delay…

Embroidered Spoof Surface Plasmon Polariton Transmission Line for Wireless Body Sensor Network

Ali Ghaddar, Baptiste Garnier, François Rault, Eric Lheurette, Ludovic Burgnies

A wearable Spoof Surface Plasmon Polariton Transmission Line (SSPP TL) operating at 2.45 GHz designed for embroidery production and on-body communication is proposed. The SSPP TL supports both even and odd modes launched by near field coupling with a dipole antenna perpendicular and parallel to the…
