Surface oxidation and oxygen incorporation in ScAlN films grown by molecular beam epitaxy

Valentina Gallardo-Mödinger, Frédéric Georgi, Xavier Wallart, Ileana Florea, Philippe Vennéguès, Yvon Cordier, Maxime Hugues

Recently, there has been much interest in the ScAlN alloy, thanks to its various potential applications in high-frequency high-power, acoustoelectric, and ferroelectric devices. Nonetheless, these applications could be impaired by the presence of oxygen in the alloy and the formation of a surface...

Spintronic Terahertz Emitters with Integrated Metallic Terahertz Cavities

Adrien Wright, Martin Mičica, Pierre Koleják, Geoffrey Lezier, Kamil Postava, Jacques Hawecker, Anna de Vetter, Jérôme Tignon, Juliette Mangeney, Henri Jaffres, Romain Lebrun, Nicolas Tiercelin, M. Vanwolleghem, Sukhdeep Dhillon

Spintronic terahertz emitters (STEs), based on optical excitation of nanometer thick ferromagnetic/heavy metal (FM/HM) heterojunctions, have become important sources for the generation of terahertz (THz) pulses [1-2] . However, the efficiency of the optical-to-THz conversion remains limited.

Closed-form solutions for wave propagation in hexagonal diatomic non-local lattices

F. Ongaro, P.H. Beoletto, F. Bosia, M. Miniaci, N.M. Pugno

Periodic mass–spring lattices are commonly used to investigate the propagation of waves in elastic systems, including wave localisation and topological protection in phononic crystals and metamaterials. Recent studies have shown that introducing non-neighbouring (i.e., beyond nearest neighbour)...

Boron-doped carbon nanowalls as effective electrodes for non-enzymatic electrochemical glucose detection: A novel bimodal EC-SALDI-MS approach

Ioana Silvia Hosu, M. Sobaszek, M. Ficek, R. Bogdanowicz, Yannick Coffinier

For the first time, boron-doped carbon nanowalls (B-CNWs) have been used as effective working electrodes for non-enzymatic electrochemical glucose detection. To achieve optimal response time and sensitivity, we activated B-CNWs by polarising them at 1.1 V in NaOH for 60 min. We established a robust...

Lagrange’s Method and Lagrangian’s Mechanism in Maxwell’s A Treatise on Electricity and Magnetism (1873)

Raffaele Pisano, Donatella Marmottini, Andrea Durlo

James Clerk Maxwell advanced Electromagnetic theory, while also mathematically enlarging Michael Faraday’s works. He declined Newtonian mechanics for the formulation of new conceptual frameworks because more adequate for describing a field of new phenomena such as electromagnetism; so he also went...

Signal estimation and uncertainties extraction in TeraHertz Time Domain Spectroscopy

Elsa Denakpo, Théo Hannotte, Noureddin Osseiran, François Orieux, Romain Peretti

<div><p>Terahertz Time Domain Spectroscopy (THz-TDS) systems have emerged as mature technologies with significant potential across various research fields and industries. However, the lack of standardized methods for signal and noise estimation and reduction hinders its full potential....

PViTGAtt-IP: Severity Quantification of Lung Infections in Chest X-rays and CT Scans via Parallel and Cross-Attended Encoders

Bouthaina Slika, Fadi Dornaika, Fares Bougourzi, Karim Hammoudi

The development of a robust and adaptive deep learning technique for the diagnosis of pneumonia and the assessment of its severity was a major challenge. Indeed, both chest X-rays (CXR) and CT scans have been widely studied for the diagnosis, detection and quantification of pneumonia. In this paper...

Étude expérimentale des modulations en régime sonique et de la génération d’interfaces temporelles dans un cristal phononique piézoélectrique contrôlable

Charles Croënne, Florian Allein, Sarah Tessier Brothelande, Jérome O Vasseur, Frédéric Giraud, Bertrand Dubus

Les propriétés de dispersion des ondes élastiques se propageant dans des cristaux phononiques piézoélectriques peuvent être modifiées grâce à de simples changements des conditions électriques imposées. Par exemple, pour un empilement d’anneaux piézoélectriques séparés par de fines électrodes, ces...
