Polarization control of THz emission using spin-reorientation transition in spintronic heterostructure

Dinar Khusyainov, Sergei Ovcharenko, Mikhail Gaponov, Arseniy Buryakov, Alexey Klimov, Nicolas Tiercelin, Philippe Pernod, Vadim Nozdrin, Elena Mishina, Alexander Sigov, Vladimir Preobrazhensky

Polarization of electromagnetic waves plays an extremely important role in interaction of radiation with matter. In particular, interaction of polarized waves with ordered matter strongly depends on orientation and symmetry of vibrations of chemical bonds in crystals. In quantum technologies, the…

Model selection for support-vector machines through metaheuristic optimization algorithms

Oumeima Ghnimi, Sofiane Kharbech, Akram Belazi, Ammar Bouallegue

A machine learning algorithm aims at designing a mathematical model based on a given training data set. Generally, the built model has a set of parameters that need to be adjusted. Since the performance of a given model depends on its settings, the parameters have to be carefully chosen through a…

SERS characterization of aggregated and isolated bacteria deposited on silver-based substrates

Cristina-Cassiana Andrei, Anne Moraillon, Eric Larquet, Monica Potara, Simion Astilean, Endre Jakab, Julie Bouckaert, Léa Rosselle, Nadia Skandrani, Rabah Boukherroub, Francois Ozanam, Sabine Szunerits, Anne Chantal Gouget-Laemmel

Surface-enhanced Raman scattering (SERS), based on the enhancement of the Raman signal of molecules positioned within a few nanometres from a structured metal surface, is ideally suited to provide bacterial-specific molecular fingerprints which can be used for analytical purposes. However, for some…

High-Q silicon nitride drum resonators strongly coupled to gates

Xin Zhou, Srisaran Venkatachalam, Ronghua Zhou, Hao Xu, Alok Pokharel, Andrew Fefferman, Mohammed Zaknoune, Eddy Collin

Silicon nitride (SiN) mechanical resonators with high quality mechanical properties are attractive for fundamental research and applications. However, it is challenging to maintain these mechanical properties while achieving strong coupling to an electrical circuit for efficient on-chip integration…

Modeling and experimental analysis of the mass loading effect on micro-ionic polymer actuators using step response identification

Iman Dadras, Sofiane Ghenna, Sébastien Grondel, Eric Cattan, Jaan Raik, Alvo Aabloo, Saoni Banerji

This paper presents a linear electrochemomechanical model for microscale ionic actuators. A frequency-domain approach is used to facilitate model interpretation, simplify model application, and accelerate the generation of actuator-specific models. A system comprising a micro PEDOT:PSS/PEO actuator…

Development of broadband high-frequency piezoelectric micromachined ultrasonic transducer array

Xu-Bo Wang, Le-Ming He, You-Cao Ma, Wen-Juan Liu, Wei-Jiang Xu, Jun-Yan Ren, Antoine Riaud, Jia Zhou

Piezoelectric micromachined ultrasonic transducers (PMUT) are promising elements to fabricate a two-dimensional (2D) array with a pitch small enough (approximately half wavelength) to form and receive arbitrary acoustic beams for medical imaging. However, PMUT arrays have so far failed to combine…

Bias-dependence of surface charge at low temperature in GaN self-switching diodes

E. Perez-Martin, I. Iniguez-De-La-Torre, T. Gonzalez, Christophe Gaquière, J. Mateos

In this work, with the help of a semi-classical two-dimensional Monte Carlo (MC) simulator, we study the DC current-voltage curves of Self-Switching Diodes (SSDs) fabricated on an AlGaN/GaN heterostructure from 100 K up to room temperature. Due to the very narrow channel of the SSDs, the presence…
