High-Frequency Noise Characterization and Modeling of Graphene Field-Effect Transistors

Marina Deng, Dalal Fadil, Wei Wei, Emiliano Pallecchi, Henri Happy, Gilles Dambrine, Magali de Matos, Thomas Zimmer, Sébastien Frégonèse

This article presents the small-signal and noise characterization of different technologies based on chemical vapor deposition (CVD) and silicon-carbide (SiC) graphene field-effect transistors (GFETs). The noise model, built on noise figure measurements under 50 Ω using the F 50 method, was…

Validating the CorrectWearing of Protection Mask by Taking a Selfie: Design of a Mobile Application “CheckYourMask” to Limit the Spread of COVID-19

Karim Hammoudi, Adnane Cabani, Halim Benhabiles, Mahmoud Melkemi

In a context of a virus that is transmissive by sputtering, wearing masks appear necessary to protect the wearer and to limit the propagation of the disease. Currently, we are facing the 2019–2020 coronavirus pandemic. Coronavirus disease 2019 (COVID-19) is an infectious disease with first symptoms…

Cyclostationary-based vital signs detection using microwave radar at 2.5 GHz

Fatima Sekak, Kawtar Zerhouni, Fouzia Elbahhar, Madjid Haddad, Christophe Loyez, Kamel Haddadi

Non-contact detection and estimation of vital signs such as respiratory and cardiac frequencies is a powerful tool for surveillance applications. In particular, the continuous wave bio-radar has been widely investigated to determine the physiological parameters in a non-contact manner. Since the RF…

Terahertz spintronic emitter with arbitrarily controllable linear polarization properties not needing a rotating magnetic bias

Pierre Kolejak, Kamil Postava, Jean-Francois Lampin, Nicolas Tiercelin, Mathias Vanwolleghem

Spintronic THz emitters are new intensively studied sources of THz radiation with high potential in broadband THz time-domain spectroscopy. We present a novel architecture for a spintronic emitter based on a ferromagnetic heterostructure with an induced in-plane magnetic anisotropy. This new…

Demonstrating full integration process for electroactive polymer microtransducers to realize soft microchips

Lauréline Seurre, Kätlin Rohtlaid, Giao T. M. Nguyen, Caroline Soyer, Sofiane Ghenna, Sébastien Grondel, Frederic Vidal, Barthelemy Cagneau, Cedric Plesse, Eric Cattan

Actuation and sensing with electroactive polymers should be a chance for flexible MEMS but their micromachining and integration are still not mature. Some innovative materials and microfabrication processes are still expected. In this paper, a first full elaboration of polymeric microtransducers (…

Power measurement setup development for on-wafer characterization at 185-191 GHz

Caroline Maye, Sylvie Lepilliet, Etienne Okada, Daniel Gloria, Guillaume Ducournau, Christophe Gaquière

This article presents off-wafer scalar power setup dedicated to load-pull measurement for characterization of on-wafer active devices between 185 and 191 GHz. The system architecture allows us to determine the absorbed input power, the output power delivered to the load, the power added efficiency…

Dispersion of IDT-induced high-frequency surface acoustic waves - Application to the mechanical and dimensional characterization of mesoporous silicon

Tahar Kadi, Marc Duquennoy, Katir Ziouche, Mohammadi Ouaftouh, Nikolay Smagin

A method based on the dispersion of surface acoustic waves (SAW) is proposed for the effective characterization of mesoporous silicon (MPS) layers with the possibility of estimating Young's modulus and the thickness of the porous layer, as well as the porosity. For this purpose, IDT were…

Atomic Structure of Glassy GeTe 4 as a Playground to Assess the Performances of Density Functional Schemes Accounting for Dispersion Forces

Pier Luigi Silvestrelli, Évelyne Martin, Mauro Boero, Assil Bouzid, Guido Ori, Carlo Massobrio

The atomic structure of glassy GeTe4 is obtained in the framework of first-principles molecular dynamics (FPMD) by considering five different approaches for the description of the electronic structure within density functional theory (DFT). Among these schemes, one is not corrected by accounting…
