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…

Magnetostatic microvalve for high momentum rate pulsed jet generation

R. Viard, Abdelkrim Talbi, Philippe Pernod, Vladimir Preobrazhensky, A. Merlen

A fully integrated magnetic driven MEMS Micro-valve providing pulsed jets was developed and characterized for active aerodynamic control. The device is composed of a microvalve, a magnetostatic actuator and a packaging allowing accurate positioning on the models or prototypes. The microvalve is a…

Characterisation and modelling of parasitic effects and failure mechanisms in AlGaN/GaN HEMTs

Nathalie Malbert, Nathalie Labat, Arnaud Curutchet, Charlotte Sury, Virginie Hoel, Jean-Claude de Jaeger, N. Defrance, Yannick Douvry, Christian Dua, Mourad Oualli, C. Bru-Chevallier, J.M. Bluet, Walf Chikhaoui

This work is a study of the degradations of AlGaN/GaN HEMTs induced by 2000 h of ageing tests. The methodology is based on cross-characterisation analysis. The life tests (HTO 150 °C, HTO 175 °C and HTRB 175 °C and Idq 90 °C) have mainly induced a decrease of the saturation drain current, occurring…

Silicon nanowires coated with silver nanostructures as ultrasensitive interfaces for surface-enhanced Raman spectroscopy

E. Galopin, J. Barbillat, Yannick Coffinier, Sabine Szunerits, G. Patriarche, Rabah Boukherroub

Silver nanoparticles (Ag NPs) were chemically deposited on silicon nanowires (SiNWs), prepared using the vapor−liquid−solid (VLS) growth mechanism, using an in situ electroless metal deposition technique. The resulting SiNWs/Ag NPs composite interfaces showed large Raman scattering enhancement for…
