Etude exploratoire du rayonnement électromagnétique causé par les contacts électriques d'un connecteur blindé

Youssef Bouri, S. Baranowski, Jean Razafiarivelo, Lamine Kone, Bernard Demoulin

Les connecteurs, blindés ou non, peuvent constituer une source de problèmes de CEM (compatibilité électromagnétique) dans un système électronique complexe. L'analyse de leur comportement électromagnétique peut permettre de quantifier et de réduire ensuite ces effets gênants en prenant en…

Crosstalk measurement of DOS-like switch using InP narrow deep-etched waveguides

Marie Lesecq, Maxime Beaugeois, Sophie Maricot, Jean-Pierre Vilcot

We report on the performance of an optical switch based on the use of narrow deep-etched InP waveguides. A DOS-like structure has been designed and fabricated. First characterization results are reported. They show an optical crosstalk value close to -20dB.

Hysteretic magnetotransport in p-type AlxGa1-xAs heterostructures with In/Zn/Au ohmic contacts

B. Grbic, R. Leturcq, T. Ihn, K. Ensslin, G. Blatter, D. Reuter, A.D. Wieck

The two-terminal magneto-conductance of a hole gas in C-doped AlGaAs/GaAs heterostructures with ohmic contacts consisting of alloyed In/Zn/Au displays a pronounced hysteresis of the conductance around zero magnetic field. The hysteresis disappears above magnetic fields of around 0.5 T and…

Detecting single-electron tunneling involving virtual processes in real time

S. Gustavsson, M. Studer, R. Leturcq, T. Ihn, K. Ensslin, D.C. Driscoll, A.C. Gossard

We use time-resolved charge detection techniques to probe virtual tunneling processes in a double quantum dot. The process involves an energetically forbidden state separated by an energy δ from the Fermi energy in the leads. The non-zero tunneling probability can be interpreted as cotunneling,…

Ultrafast electron-phonon decoupling in graphite

K. Ishioka, M. Hase, M. Kitajima, L. Wirtz, A. Rubio, H. Petek

We report the ultrafast dynamics of the 47.4 THz coherent phonons of graphite interacting with a photoinduced non-equilibrium electron-hole plasma. Unlike conventional materials, upon photoexcitation the phonon frequency of graphite upshifts, and within a few picoseconds relaxes to the stationary…

Relation between reversible electrowetting and impacting/bouncing drop test on superhydrophobic surfaces

Florian Lapierre, V. Thomy, Philippe Brunet, Yannick Coffinier, Rabah Boukherroub

The wetting properties of liquid droplets behavior on superhydrophobic surfaces is still a challenging issue. Functional surfaces with controlled wetting properties, which can respond to external stimuli, have attracted huge interest of the scientific community due to their wide range of potential…

Structural health monitoring using cross-correlation of an ambient noise field

Najib Abou Leyla, Emmanuel Moulin, Jamal Assaad, Sébastien Grondel, Pascal Poussot

Theoretical and experimental studies in underwater acoustic, seismology and more recently ultrasonic have demonstrated that an estimate of the Time Domain Green Function (TDGF) between two receivers could be obtained from the cross-correlation of a diffuse acoustic noise field of these two…
