Experimental analysis of dense multipath components in an industrial environment

Emmeric Tanghe, Davy Gaillot, M. Lienard, Luc Martens, Wout Joseph

This work presents an analysis of dense multipath components (DMC) in an industrial workshop. Radio channel sounding was performed with a vector network analyzer and virtual antenna arrays. The specular and dense multipath components were estimated with the RiMAX algorithm. The DMC covariance…

Band gap formation and elastic wave transmission in two-dimentional surface phononic crystal

Sergey Yankin, Abdelkrim Talbi, Yu Du, Jean-Claude Gerbedoen, Vladimir Preobrazhensky, Philippe Pernod, Olivier Bou Matar

Using finite element method analysis of surface acoustic wave (SAW) propagation in the phononic crystal in a form of periodic lattice from nickel pillars, located on a piezoelectric substrate of Y+128°-cut LiNbO3, has been conducted. Amplitude and phase characteristics of SAW propagation through…

High frequency acoustic for nanostructures wetting characterization

Sizhe Li, Sébastien Lamant, Julien Carlier, Malika Toubal, Pierre Campistron, Xiumei Xu, Guy Vereecke, Vincent Senez, V. Thomy, Bertrand Nongaillard

Nanostructure wetting is a key problem when developing superhydrophobic surfaces. Conventional methods do not allow us to draw conclusions about the partial or complete wetting of structures on the nanoscale. Moreover, advanced techniques are not always compatible with an in situ, real time,…

Enhancement of energy storage in epitaxial PbZrO3 antiferroelectric films using strain engineering

Jun Ge, Denis Remiens, Xianlin Dong, Ying Chen, Jean Costecalde, Feng Gao, Fei Cao, Genshui Wang

We demonstrate an approach to enhance the energy storage density W of antiferroelectric film through simple altering a crystallographic orientation of the substrate. We reveal that the antiferroelectric phase stability of PbZrO3 can be enhanced for the (110) or (111) SrTiO3 substrate orientation,…

Cyclones and attractive streaming generated by acoustical vortices

Antoine Riaud, Michael Baudoin, Jean-Louis Thomas, Olivier Bou Matar

Acoustical and optical vortices have attracted great interest due to their ability to capture and manipulate particles with the use of radiation pressure. Here we show that acoustical vortices can also induce axial vortical flow reminiscent of cyclones, whose topology can be controlled by adjusting…

Interface dipole : effects on threshold voltage and mobility for both amorphous and poly-crystalline organic field effect transistors

C. Celle, C. Suspène, M. Ternisien, S. Lenfant, David Guérin, K. Smaali, K. Lmimouni, J.P. Simonato, Dominique Vuillaume

We report a detailed comparison on the role of a self-assembled monolayer (SAM) of dipolar molecules on the threshold voltage and charge carrier mobility of organic field-effect transistor (OFET) made of both amorphous and polycrystalline organic semiconductors. We show that the same relationship…

Dual mechanical behaviour of hydrogen in stressed silicon nitride thin films

F. Volpi, M. Braccini, Arnaud Devos, G. Raymond, A. Pasturel, Pascal Morin

In the present article, we report a study on the mechanical behaviour displayed by hydrogen atoms and pores in silicon nitride (SiN) films. A simple three-phase model is proposed to relate the physical properties (stiffness, film stress, mass density, etc.) of hydrogenated nanoporous SiN thin films…
