Microfluidic microsystem for magnetic sensing of nanoparticles with giant magneto-impedance technology

Matthieu Denoual, M. Harnois, Sébastien Saez, Christophe Dolabdjian, V. Senez

We have fabricated a microfluidic microsystem integrating a Giant Magneto-Impedance wire sensor that successfully detected the passage of magnetic nanoparticules in liquid medium. Giant Magneto-Impedance microwire sensors consisted in CoFeSiBNb alloy, 40 μm diameter and 1 cm long wires. By...

Development of interdigital transducer sensors for non-destructive characterization of thin films using high frequency Rayleigh waves

J. Deboucq, Marc Duquennoy, Mohammadi Ouaftouh, Frédéric Jenot, Julien Carlier, Mohamed Ourak

In this paper, Rayleigh waves were generated and studied over a broad frequency range (5–50 MHz) and from the dispersion phenomenon, two substrate on layer type-samples with thin layer thicknesses of 1 μm and 500 nm, respectively, were characterized. The originality in this paper is the use of...

Dispersion of confined acoustic phonons in ultra-thin Si membranes

J. Cuffe, E. Chavez, P.O. Chapuis, E.H. El Boudouti, F. Alzina, D. Dudek, Yan Pennec, Bahram Djafari-Rouhani, A. Shchepetov, M. Prunnila, J. Ahopelto, C.M. Sotomayor Torres

The acoustic phonon dispersion curves of ~10 and ~30 nm Si membranes were measured using Brillouin Light Scattering (BLS) spectroscopy. The dispersion relations of the confined phonons were calculated from a semi-analytical model based on continuum elasticity theory. Green’s function simulations...

Optical waveguide loss minimized into gallium nitride based structures grown by metal organic vapor phase epitaxy

A. Stolz, E. Cho, El Hadj Dogheche, Yidir Androussi, David Troadec, Dimitris Pavlidis, Didier Decoster

The waveguideproperties are reported for wide bandgap gallium nitride(GaN) structures grown by metal organic vapor phase epitaxy on sapphire using a AlN/GaN short period-superlattice (SPS) buffer layer system. A detailed optical characterization of GaN structures has been performed using the prism...

Contact angle hysteresis origins: investigation on super-omniphobic surfaces

Renaud Dufour, Maxime Harnois, Vincent Thomy, Rabah Boukherroub, Vincent Senez

Contact angle hysteresis of liquid droplets is investigated on sticky and flexible super-omniphobic surfaces made up of PDMS–Si3N4 microstructures. Up to now, extensive studies have been focusing on the relation between hysteresis and surface properties such as roughness or defect density. However...
