[Invited] High frequency electronic devices : impact of beyond graphene materials

Henri Happy, D. Mele, Ivy Colambo, Mohamed Salah Khenissa, Mohamed Moez Belhaj, Emiliano Pallecchi, Abdelkarim Ouerghi, Dominique Vignaud, Gilles Dambrine

Considering graphene field effect transistors (GFETs), considerable efforts have been made during the recent years to reach impressive current gain cut-off frequency (ft) over 400 GHz. Unfortunately, for these devices, the maximum frequency of oscillation (fmax) remains under 100GHz. This deviation…

A MIMO random channel generator for indoor power-line communication

Kassim Khalil, Marc G. Gazalet, Patrick Corlay, François-Xavier Coudoux, M Gharbi

Multiple-input multiple-output (MIMO) technology has already been used in power-line communication (PLC). An accurate description of MIMO channels for PLC network topologies is of great interest and importance in the development and testing of digital communication algorithms. However, the…

Effect of thickness and deposition rate on the structural and magnetic properties of evaporated Fe/Al thin films

M. Mebarki, A. Layadi, L. Kerkache, A. Benabbas, Nicolas Tiercelin, Vladimir Preobrazhensky, Philippe Pernod

We report experimental results on the structural and magnetic properties of Fe thin films deposited by thermal evaporation onto polycrystalline Al substrates. The effect of thickness t (in the 76 to 431 nm range) and deposition rate are investigated. The texture, the strain, and the grain size…

Hypersonic band gap in an AlN-TiN bilayer phononic crystal slab

S. Hemon, Abdellatif Akjouj, A. Soltani, Yan Pennec, Y. El Hassouani, Abdelkrim Talbi, V. Mortet, Bahram Djafari-Rouhani

We show both theoretically and experimentally the existence of a complete band gap in a phononic crystal (PnC) constituted by periodical air holes drilled in a solid bi-layer slab. The composite slab is formed with an aluminum nitride (AlN) layer deposited on a titanium nitride (TiN) thin metallic…

Low work function thin film growth for high efficiency thermionic energy converter : coupled Kelvin probe and photoemission study of potassium oxide

François Morini, Emmanuel Dubois, J.F. Robillard, Stéphane Monfray, Thomas Skotnicki

Recent researches in thermal energy harvesting have revealed the remarkable efficiency of thermionic energy converters comprising very low work function electrodes. From room temperature and above, this kind of converter could supply low power devices such as autonomous sensor networks. In this…

Geometrical optics-based model for dielectric constant and loss tangent free-space measurement

Kamel Haddadi, Tuami Lasri

A microwave free-space reflection method for determining the complex permittivity of planar dielectric materials is demonstrated. The method makes use of the measurement of the near-field microwave reflection coefficient of a metal-backed sample. The modeling of the structure and its calibration…

On detection method for soft iterative decoding in the presence of impulsive interference

Vincent Dimanche, Alban Goupil, Laurent Clavier, Guillaume Gelle

This paper deals with the performance improvement of soft iterative decoders in impulsive interference modeled by additive noise. In case of $alpha$-stable noise, the inputs of the belief propagation decoder are too complex to compute. We propose to use an approximation of the log likelihood ratio…
