Electron energy loss spectroscopy determination of Ti oxidation state at the (001) LaAlO3/SrTiO3 interface as a function of LaAlO3 growth conditions

Jean-Luc Maurice, Gervasi Herranz, Christian Colliex, Isabelle Devos, Cécile Carrétéro, Agnès Barthelemy, Karim Bouzehouane, Stéphane Fusil, Dominique Imhoff, Éric Jacquet, François Jomard, Dominique Ballutaud, Mario Basletic

At the (001) interface between the two band-insulators LaAlO3 and SrTiO3, a high-mobility electron gas may appear, which has been the object of numerous works over the last four years. Its origin is a subject of debate between the interface polarity and unintended doping. Here we use electron...

Low Voltage Totally Free Flexible RF MEMS Switch With Anti-Stiction System

Salim Touati, Nicolas Lorphelin, Alexandre Kanciurzewski, Renaud Robin, A.-S. Rollier, Olivier Millet, Karim Segueni

This paper concerns a new design of RF MEMS switch combined with an innovative process which enable low actuation voltage (<5V) and avoid stiction. First, the structure described with principal design issues, the corresponding anti-stiction system is presented and FEM simulations are done. Then...

Hypersound damping in vitreous silica measured by picosecond acoustics

Arnaud Devos, M. Foret, S. Ayrinhac, P. Emery, B. Rufflé

The attenuation of longitudinal acoustic phonons up to frequencies nearing 250 GHz is measured in vitreous silica with a picosecond optical technique. By taking advantage of interferences on the probe beam, difficulties encountered in early pioneering experiments are alleviated. Sound damping at...

Influence of electronic structure and multiexciton spectral density on multiple-exciton generation in semiconductor nanocrystals : tight-binding calculations

Guy Allan, Christophe Delerue

Several experimental works have reported that a single high-energy photon could generate multiple excitons in semiconductor nanocrystals and several theories have been proposed to explain these results. Using a tight-binding method, we calculate the electronic structure of InAs, Si, and PbSe...

Magnitude modulation of microwave signals by ultrafast control of membrane LT-GaAs photo switching devices

Charlotte Tripon-Canseliet, Salim Faci, Georges Alquié, Karine Blary, Stéphane Formont, Jean Chazelas

Microwave photonics contributes through ultrafast devices to the processing of high data rates. In this area, microwave photoconductive switches (MPCSs) in integrated technology have proved their performances to control the transmission of high frequency signals in complex systems. A description of...
