New applications of magneto-acoustic phase conjugation

Vladimir Preobrazhensky, Yuri Pyl'Nov, Philippe Pernod, Nikolay Smagin, Alain Merlen

The results of theoretical and experimental studies of application of parametric wave phase conjugation (WPC) for ultrasonic velocimetry of flows are reported. 3D-simulation of propagation of phase conjugate waves (PCW) in nonlinear and moving media is developed. Break of time reversal invariance…

To grate a liquid into tiny droplets by its impact on a hydrophobic microgrid

P. Brunet, F. Lapierre, Farzam Zoueshtiagh, V. Thomy, A. Merlen

We report on experiments of drop impacting a hydrophobic micro-grid, of typical spacing a few tens of µm. Above a threshold in impact speed, liquid emerges to the other side, forming microdroplets of size about that of the grid holes. We propose a method to produce either a mono-disperse spray or a…

Universality of bias- and temperature-induced dephasing in ballistic electronic interferometers

Y. Yamauchi, M. Hashisaka, S. Nakamura, K. Chida, S. Kasai, T. Ono, R. Leturcq, K. Ensslin, D.C. Driscoll, A.C. Gossard, K. Kobayashi

We performed a transport measurement in a ballistic Aharonov-Bohm ring and a Fabry-P´erottype interferometer. In both cases we found that the interference signal is reversed at a certain bias voltage and that the visibility decays exponentially as a function of temperature, being in a strong…

A millimeter-wave microstrip antenna array on ultra-flexible micromachined polydimethylsiloxane (PDMS) polymer

S. Hage-Ali, Nicolas Tiercelin, P. Coquet, R. Sauleau, H. Fujita, Vladimir Preobrazhensky, Philippe Pernod

The use of Polydimethylsiloxane (PDMS), an ultra flexible polymer, as a substrate for the realization of reconfigurable microwave devices in the 60-GHz band is presented. As bulk PDMS is demonstrated to be lossy at millimeter waves, membrane-supported devices are considered. A new reliable and…

Synthesis and luminescence properties of (N-Doped) ZnO nanostructures from a dimethylformamide aqueous solution

B. Sieber, Hong Liu, G. Piret, J. Laureyns, P. Roussel, B. Gelloz, Sabine Szunerits, Rabah Boukherroub

The paper reports on the optical properties of ZnO nanostructures elaborated on a zinc foil substrate by a simple chemical approach. The doping type and density of the ZnO nanostructures were evaluated using electrochemical impedance spectroscopy. XRD diffraction patterns and Raman spectroscopy…

Novel bondpad report process for III-V semiconductor devices using full HSQ properties

Malek Zegaoui, Nargess Choueib, P. Tilmant, Marc François, Christiane Legrand, Jean Chazelas, Didier Decoster

This paper reports on an easy and quick planarization and passivation technique of III-V compound semiconductor compatible with nanoscale devices. Vertical etching requires good sidewalls passivation to reduce drastically the leakage current and to obtain a good planarization of the devices for…
