Characterization and Electrical Modeling Including Trapping Effects of AIN/GaN HEMT 4×50μm on Silicon Substrate

Mohamed Bouslama, Ahmad Al Hajjar, Raphaël Sommet, Jean-Christophe Nallatamby, F Medjdoub

This paper reports the full characterization and modeling of novel AlN/GaN HEMTs on silicon using a short gate length. This device has been optimized for high frequency analog circuits applications. The presented model includes DC and small-signal modeling steps taking into account the trapping…

Resolving the Controversial Existence of Silicene and Germanene Nanosheets Grown on Graphite

Wenbing Peng, Tao Xu, Pascale Diener, Louis Biadala, Maxime Berthe, Xiaodong Pi, Yves Borensztein, Alberto Curcella, Romain Bernard, Geoffroy Prévot, B. Grandidier

The highly oriented pyrolytic graphite (HOPG) surface, consisting of a dangling bond-free lattice, is regarded as a potential substrate for van der Waals heteroepitaxy of two-dimensional layered materials. In this work, the growth of silicon and germanium on HOPG is investigated with scanning…

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,…

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…

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…

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…
