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...

Effects of Na2SO4 on the optical and structural properties of Cu2ZnSnS4 thin films synthesized using co-electrodeposition technique

Hassan Kirou, Lahoucine Atourki, Khadija Abouabassi, Ali Soltani, Abdelmajid Almaggoussi, Abdeslam Elfanaoui, Khalid Bouabid, M'Barek Nya, Ahmed Ihlal

Abstract In this paper, kesterite films have been prepared by sulfurization of co-electrodeposited Cu–Zn–Sn (CZT) precursor using Na2SO4 as a complexing agent. The structural, morphological, optical and electrical properties of the films have been investigated in details. Adherent layers and pure...

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...

Towards high-transconductance graphene high-speed biosensors

W. Wei, S. Mhedbhi, P. Tilmant, H. Happy, E. Pallecchi

Graphene is a new material that is promising for application in microwave electronics as it features high mobility and is compatible with standard nanofabrications techniques. Graphene is also extremely sensitive to the environment due to its two dimensional nature, is mechanically robust,...

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...

Control of local wetting by microscopic particles

Lizhong Mu, Harunori N. Yoshikawa, Daichi Kondo, Tetsuya Ogawa, Mayu Kiriki, Farzam Zoueshtiagh, Masahiro Motosuke, Toshihiro Kaneko, Ichiro Ueno

We perform experiments to investigate how particles of micro-meter size modify the wetting of a completely wettable solid surface. The motion of a macroscopic contact line (MCL) is observed to be altered in the region surrounding the particles. The MCL is accelerated locally by a single particle to...
