Fatigue test on flexible graphene field effect transistors with bottom gate electrode

Wei Wei, Dalal Fadil, Sarra Mhedhbi, Soukaina Ben Salk, Emiliano Pallecchi, Henri Happy

Graphene is a promising candidate as channel material for flexible wearable radio frequency devices. In this work we fabricated double gate flexible graphene field effect transistors and characterized their DC and RF performance. Moreover, we performed a fatigue test consisting on a 1000 times...

Chapitre d'ouvrage

Chapter 1 - Interface response theory

L. Dobrzynski, Abdellatif Akjouj, El Houssaine El Boudouti, Housni Al-Wahsh, Bahram Djafari-Rouhani, Gaëtan Lévêque, Yan Pennec

A general theory of interface response in linear composite systems is presented in the first chapter of this book on phononics. Specific examples, fully developed in the next chapters of this book, are shortly presented in this chapter. Other examples using this general interface response theory...

Electron and Hole g-Factors and Spin Dynamics of Negatively Charged Excitons in CdSe/CdS Colloidal Nanoplatelets with Thick Shells

Elena V. Shornikova, Louis Biadala, Dmitri R. Yakovlev, Donghai Feng, Victor F. Sapega, Nathan Flipo, Aleksandr A. Golovatenko, Marina A. Semina, Anna V. Rodina, Anatolie Mitioglu, Mariana V. Ballottin, Peter C. M. Christianen, Yuri G. Kusrayev, Michel Nasilowski, Benoit Dubertret, Manfred Bayer

We address spin properties and spin dynamics of carriers and charged excitons in CdSe/CdS colloidal nanoplatelets with thick shells. Magneto-optical studies are performed by time-resolved and polarization-resolved photoluminescence, spin-flip Raman scattering and picosecond pump-probe Faraday...

A validated simulation of energy harvesting with piezoelectric cantilever beams on a vehicle suspension using Bond Graph approach

Barbara Lafarge, Sébastien Grondel, Christophe Delebarre, Eric Cattan

Nowadays, there is a combine effect of piezoelectric material performances and energy harvesting management strategy increase. As the same time, the energy consumption of electrical components and circuits decrease. Thus, this leads to a growing interest in recovering low energy level with...

Device-free human activity microwave detection

Kamel Haddadi, Christophe Loyez

This work describes a device-free activity detection method using a 2.45 GHz link associated to a short-time Fourier transform algorithm. Detection of human activities are exemplary demonstrated to validate the proposed approach considering several scenarios. The simplicity of hardware/software...

High-resolution THz gain measurements in optically pumped ammonia

Martin Mičica, Sophie Eliet, Mathias Vanwolleghem, Roman Motiyenko, Anastasia Pienkina, Laurent Margulès, Kamil Postava, Jaromír Pištora, Jean-Francois Lampin

This study is aimed at the evaluation of THz gain properties in an optically pumped NH$_3$ gas. NH$_3$ molecules undergo rotational-vibrational excitation by mid-infrared (MIR) optical pumping provided by a MIR quantum cascade laser (QCL) which enables precise tuning to the NH3 infrared transition...
