Magnetostatic micro-actuator based on ultrasoft elastomeric membrane and copper-permalloy electrodeposited structures

Jérémy Streque, Abdelkrim Talbi, Clément Bonnerot, Philippe Pernod, Vladimir Preobrazhensky

This paper presents different designs of magnetostatic micro-actuators, based on both conventional and integrated micro-coils. A 3-dimensional magnetic circuit made of Permalloy is proposed in order to improve their efficiency. The mobile parts of the micro-actuators are made of ultrasoft…

Dual-purpose BGaN layers on performance of nitride-based high electron mobility transistors

Vinod Ravindran, Mohamed Boucherit, Ali Soltani, Simon Gautier, Tarik Moudakir, Jeramy Dickerson, Paul L. Voss, Marie-Antoinette Di Forte-Poisson, Jean-Claude de Jaeger, Abdallah Ougazzaden

A GaN/ultrathin BGaN/GaN heterojunction is used in AlGaN/GaN high electron mobility transistors (HEMTs) to provide an electrostatic barrier to electrons and to improve the confinement of the 2-dimensional electron gas. BGaN back-barrier layers limit leakage in the GaN buffer thanks to two effects:…

Level repulsion and evanescent waves in sonic crystals

V. Romero-Garcia, Jerome O. Vasseur, Anne-Christine Hladky, Lluis Miquel Garcia-Raffi, J.V. Sanchez-Perez

This work theoretically and experimentally reports the evanescent connections between propagating bands in periodic acoustic materials. The complex band structures obtained by solving for the k(ω) problem reveal a complete interpretation of the propagation properties of these systems. The…

The transverse electromagnetic horn antenna as an efficient THz pulse emitter

Jean-Francois Lampin, Emilien Peytavit, Tahsin Akalin, Guillaume Ducournau, Jens Klier, Sabine Wohnsiedler, Joachim Jonuscheit, René Beigang

We have fabricated a new photoconductive antenna based on a transverse electromagnetic horn and low temperature grown GaAs. It has been tested with a time-domain terahertz setup. The horn was used as the emitter and a standard dipole photoconductive antenna was used as the receiver. The spectrum…

A 300 GHz InP/GaAsSb/InP HBT for high data rate applications

Maher, Hassan, Vincent Delmouly, U. Rouchy, Michel Renvoisé, Peter Frijlink, Derek Smith, M. Zaknoune, Damien Ducatteau, Vanessa Avramovic, André Scavennec, Jean Godin, Muriel Riet, Cristell Maneux, Bertrand Ardouin

In this paper, a fully passivated InP/GaAsSb/InP DHBT on InP substrate with excellent DC and RF performance is developed. The epi-layers are grown by the MOCVD technique, with a base layer of 25nm and a collector layer of 130nm. The emitter width of the transistor is 0.35μm and the base contact is…
