Impact Of Substrate And Post-Annealing Temperatures On The Refractive Index And Crystallinity Of Lead-Free BCTZ Thin Films, Impact du substrat et des températures de recuit post-dépôt sur l'indice de réfraction et la cristallinité des couches minces sans plomb de BCTZ

Yusuf Kerem Bostan, F Jean, Fahrettin Sarcan, E Hut, A Erol, D Remiens, J Teng, E Dogheche

In this study, we investigated the effects of substrate temperature and post-annealing treatment (P.A.T.) on the refractive index of lead-free Ba₀.₈₅Ca₀.₁₅Ti₀.₉Zr₀.₁O₃ (BCTZ) thin films synthesized by magnetron RF sputtering. Our results indicate that both the in-situ substrate temperature and the…, Dans cette étude, nous avons étudié les effets de la température du substrat et du traitement de recuit post-dépôt (P.A.T.) sur l’indice de réfraction des couches minces sans plomb de Ba₀.₈₅Ca₀.₁₅Ti₀.₉Zr₀.₁O₃ (BCTZ) synthétisées par pulvérisation magnétron RF. Nos résultats indiquent que la…

Robust DNNs for power allocation problems in cognitive relay networks

Yacine Benatia, Anne Savard, Romain Negrel, E Veronica Belmega

<div><p>In this paper, we investigate deep neural network (DNN)-based power allocation policies maximizing the opportunistic rate of a relay-aided cognitive radio network under a quality of service (QoS) constraint protecting the primary transmission. The full-duplex relay performs…

Optimization of Non-Alloyed Backside Ohmic Contacts to N-Face GaN for Fully Vertical GaN-on-Silicon-Based Power Devices

Youssef Hamdaoui, Sofie S T Vandenbroucke, Sondre Michler, Katir Ziouche, Matthias M Minjauw, Christophe Detavernier, Farid Medjdoub

In the framework of fully vertical GaN-on-Silicon device technology development, we report on the optimization of non-alloyed ohmic contacts on the N-polar n+-doped GaN face backside layer. This evaluation is made possible by using patterned TLMs (Transmission Line Model) through direct laser…

Parametrically enhancing sensor sensitivity at an exceptional point

P. Djorwé, M. Asjad, Y. Pennec, D Dutykh, B Djafari-Rouhani

<div><p>We propose a scheme to enhance the sensitivity of non-Hermitian optomechanical mass sensors. The benchmark system consists of two coupled optomechanical systems where the mechanical resonators are mechanically coupled. The optical cavities are driven either by a blue-detuned or…

Deep eutectic solvents : from structural and high frequency characterization to antimicrobial applications, Solvants eutectiques profonds : de la caractérisation structurelle et à haute fréquence aux applications antimicrobiennes

Tomasz Swebocki

In a world dominated by microbes, humans represent only a small fraction of living organisms. Some microbes are beneficial, but others, such as antibiotic-resistant bacteria, pose a major threat. In 2019, about 8.88 million deaths were attributed to bacterial sepsis, including 4.95 million related…, Dans un monde dominé par des microbes, les humains ne représentent qu'une petite fraction des organismes vivants. Certains microbes sont bénéfiques, mais d'autres, comme les bactéries résistantes aux antibiotiques, posent une menace majeure. En 2019, environ 8,88 millions de décès ont été…

Tuning Deposition Conditions for VN Thin Films Electrodes for Microsupercapacitors: Influence of the Thickness

Allan Lebreton, Jérémy Barbé, Christophe Lethien, Jonathan N Coleman, Thierry Brousse

Vanadium nitride is a highly promising material for micro-pseudocapacitors when used as a bifunctional thin film, i.e. an electrode material and a current collector, owing to its remarkable electrical and electrochemical properties. However, the specific limitations associated with high-rate…
