GaN RF and power research at IEMN

F Medjdoub

GaN high electron mobility transistors (HEMT) are becoming the mainstream for high frequency and power switching applications. Devices and circuits based on these emerging materials are more suited to operate at higher voltages and temperatures than Si-based devices owing to their superior physical...

Silicon nanowire-hydrogenated TiO2 core-shell arrays for stable electrochemical micro-capacitors

Yasmina Bencheikh, Ahmed Addad, Yannick Coffinier, Umesh Kumar, Pascal Roussel, Sabine Szunerits, Toufik Hadjersi, Mohammed Amin, Seddik El Hak Abaidia, Rabah Boukherroub

In this paper, we fabricated silicon nanowire-TiO2 core-shell arrays in a two-step process. First, silicon nanowire arrays (SiNW) were prepared in HF/AgNO3 aqueous solution using metal-assisted chemical etching of bulk silicon. Then, atomic layer deposition (ALD) technique was applied to coat a 20...

Fortran Package Manager: Toward a rich ecosystem of Fortran packages

Sebastian Ehlert, Ondřej Čertík, Milan Curcic, Jakub Jelínek, Laurence Kedward, Vincent Magnin, Emanuele Pagone, Brad Richardson, John Urban

Fortran is the oldest programming language still in use today, targeting high-performance scientific and engineering applications. Traditionally, Fortran software has used build systems that are not portable or are difficult to use or extend. This has presented a significant barrier to entry for...

Periodic Structures, Irreducible Brillouin Zone, Dispersion Relations and the Plane Wave Expansion Method

Jerome O. Vasseur

The Plane Wave Expansion (PWE) method allows the calculation of dispersion curves, i.e., the relation linking the frequency to the wave number for any propagating mode of periodic structures made of elastic materials such as phononic crystals. The method is relatively easy to implement numerically...

An Analytical Model of the End-to-End Performance for Linear Video Delivery Under Bandwidth Constraints

Anthony Trioux, M Gharbi, François-Xavier Coudoux, Patrick Corlay

Recently, Linear Video Coding and Transmission (LVCT) schemes have been proposed as an alternative to traditional video transmission schemes, the latter experiencing cliff-effect [3] in wireless error-prone environments. In this paper, we propose an analytical model to estimate/predict the end-to-...

Ultra-high areal capacitance and high rate capability RuO2 thin film electrodes for 3D micro-supercapacitors

Bouchra Asbani, Gaëtan Buvat, Jeremy Freixas, Marielle Huvé, David Troadec, Pascal Roussel, Thierry Brousse, Christophe Lethien

To power the next generation of miniaturized electronic devices, 3D micro-supercapacitors are a new class of millimeter scale electrochemical capacitors with superior storage performance than their planar counterparts. Nevertheless, it is mandatory to carefully match the dimensions of the 3D...

Nanofluids dynamic viscosity evolution using high-frequency acoustic waves: application applied for droplet evaporation

Ibrahim Zaaroura, Malika Toubal, Julien Carlier, Souad Harmand, Bertrand Nongaillard

Many interests are shown on nanofluids as it's suitable for cooling applications. Knowing the physical properties of nanofluids such as viscosity plays a key role in practical heat transfer situations. The main goal of this work is to measure the dynamic viscosity of Gold nanofluids during...

Enhanced CRC-based correction of multiple errors with candidate validation

Vivien Boussard, Stéphane Coulombe, François-Xavier Coudoux, Patrick Corlay

Cyclic redundancy checks (CRC) are widely used in transmission protocols to detect whether errors have altered a transmitted packet. It has been demonstrated in the literature that CRC can also be used to correct transmission errors. In this paper, we propose an improvement of the state-of-the-art...

Optimization of spider web-inspired phononic crystals to achieve tailored dispersion for diverse objectives

Vinícius F Dal Poggetto, Federico Bosia, M. Miniaci, Nicola M Pugno

Spider orb webs are versatile multifunctional structures with optimized mechanical properties for prey capture, but also for transmitting vibrations. The versatility of such a system mainly derives from its variable geometry, which can be effectively used to design phononic crystals, thus...

Application of Combined Geophysical Methods for the Examination of a Water Dam Subsoil

Tomislaw Golebiowski, Bogdan Piwakowski, Michał Ćwiklik, Antoni Bojarski

The paper presents the results of geophysical measurements that were carried out in the vicinity of the water dam/water reservoir supplying the city of Bielsko-Biala with drinking water. The measurements were performed in order to non-invasively detect faults, fractured zones and areas filled with...
