Near Kohn anomalies in the phonon dispersion relations of lead chalcogenides

Ondrej Kilian, Guy Allan, Ludger Wirtz

We present ab-initio phonon dispersion relations for the three lead chalcogenides PbS, PbSe, and PbTe. The acoustic branches are in very good agreement with inelastic neutron-scattering data and calculations of the specific heat give good agreement with experimental data. The pronounced minimum of...

Static and dynamic properties of thin films with space charges

Laurent Baudry

The physic of ferroelectric materials is supported by many key concepts connected with both experimental behaviors and theoretical approaches. One of them is especially important: the existence of space charges in ferroelectric materials. It has been firstly reported in the litterature about half a...

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...

Electrochemical impedance spectroscopy of ZnO nanostructures

Hong Liu, G. Piret, B. Sieber, J. Laureyns, P. Roussel, Wei-Jiang Xu, Rabah Boukherroub, Sabine Szunerits

The paper reports on the use of electrochemical impedance spectroscopy to determine the doping character and carrier density of freshly prepared and annealed ZnO nanostructures. The ZnO nanostructures were obtained by chemical oxidation of metallic Zn in a 5% N,N-dimethylformamide (DMF) aqueous...

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...
