Molecular beam epitaxial growth of multilayer 2D-boron nitride on Ni substrates from borazine and plasma-activated nitrogen

Jawad Hadid, Ivy Colambo, Jose Avila, Aexandre Plaud, Christophe Boyaval, D. Deresmes, Nicolas Nuns, Pavel Dudin, Annick Loiseau, Julien Barjon, Xavier Wallart, Dominique Vignaud

2D boron nitride (2D-BN) was synthesized by gas-source molecular beam epitaxy on polycrystalline and monocrystalline Ni substrates using gaseous borazine and active nitrogen generated by a remote plasma source. The excess of nitrogen atoms allows to overcome the thickness self-limitation active on…

[Review] The role of the surface ligand on the performance of electrochemical SARS-CoV-2 antigen biosensors

Sabine Szunerits, Quentin Pagneux, Abir Swaidan, Vladyslav Mishyn, Alain Roussel, Christian Cambillau, David Devos, Ilka Engelmann, Enagnon Kazali Alidjinou, Henri Happy, Rabah Boukherroub

Point-of-care (POC) technologies and testing programs hold great potential to significantly improve diagnosis and disease surveillance. POC tests have the intrinsic advantage of being able to be performed near the patient or treatment facility, owing to their portable character. With rapid results…

Rayleigh Modes Generated by Laser-Ultrasonics at the Film-Substrate Interface for the Study of Adhesion

Martin Robin, Meriem Chrifi Alaoui, Frédéric Jenot, Mohammadi Ouaftouh, Marc Duquennoy

Adhesion testing of film-on-substrate structures by surface acoustic waves is a complex issue. Indeed, the fluctuations of some parameters like the film thickness can lead to misinterpretation of the experimental results. Additionally, in laser-ultrasonics, the positions of the generation and…

Sub-nanosecond pulse technology applied to millimetre wave systems for TDoA-based geolocalization

Christophe Loyez, Michael Bocquet, Nathalie Rolland, Kamel Haddadi

This study deals with a geolocation system that uses sub-nanosecond pulsed radio signals. Based on Time Difference of Arrival (TDoA), it allows the localization of 60-GHz transmitters in an indoor environment with an accuracy compatible with the requirements of the next generation of communicating…

Nanoprobe study of the electric field driven insulator-to-metal transition in GaMo4S8

H. Koussir, Isabelle Lefebvre, Maxime Berthe, Y. Chernukha, J. Tranchant, B. Corraze, Etienne Janod, Laurent Cario, B. Grandidier, Pascale Diener

The resistive switching observed under electric pulses in Mott materials has a high potential for micro and nanoelectronics. Here we report on the study of the resistive switching observed at the surface of single crystals of the canonical Mott semiconductor GaMo4S8. The study is made using a…

Unsupervised deep learning to solve power allocation problems in cognitive relay networks

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

In this paper, an unsupervised deep learning approach is proposed to solve the constrained and non-convex Shannon rate maximization problem in a relay-aided cognitive radio network. This network consists of a primary and a secondary user-destination pair and a secondary full-duplex relay performing…

Contactless Rheology of Soft Gels over a Broad Frequency Range

Zaicheng Zhang, Muhammad Arshad, Vincent Bertin, Samir Almohamad, Elie Raphaël, Thomas Salez, Abdelhamid Maali

We report contactless measurements of the viscoelastic rheological properties of soft gels. The experiments are performed using a colloidal-probe Atomic Force Microscope (AFM) in a liquid environment and in dynamic mode. The mechanical response is measured as a function of the liquid gap thickness…

Combined surface x-ray diffraction and density functional theory study of the germanene/Al(111)-(7×7) R19.1° structure

K. Zhang, M.C. Hanf, D. Sciacca, Romain Bernard, Yves Borensztein, A. Resta, Yves Garreau, A. Vlad, A. Coati, Isabelle Lefebvre, M. Derivaz, C. Pirri, P. Sonnet, R. Stephan, G. Prévot

Several studies have reported the possible growth of germanene on various metal surfaces. However, the exact structure of the layers formed upon evaporation at or above room temperature remains controversial. In particular, the layers obtained after Ge deposition on Al(111) have been either…

Coupling Capacitively Distinct Mechanical Resonators for Room-Temperature Phonon-Cavity Electromechanics

Alok Pokharel, Hao Xu, Srisaran Venkatachalam, Eddy Collin, Xin Zhou

Coupled electromechanical resonators that can be independently driven/detected and easily integrated with external circuits are essential for exploring mechanical modes based signal processing and multifunctional integration. One of the main challenges lies in controlling energy transfers between…
