Optimization of electrodes design for PZT thin-film actuated membranes

F. Casset, H. Michaud, T. Ricart, G. Le Rhun, M. Cueff, J. Abergel, P. Ancey, D. Faralli, Arnaud Devos, S. Fanget, E. Defay

This paper reports on the optimization of electrodes design for sol-gel Pb(Zr0.52, Ti0.48)O3 (PZT) thin-film actuated-membranes. PZT can be used in many actuator applications such as micro mirror, RF MEMS, inkjet or loudspeaker due to its strong piezoelectric properties. We aim to design membrane-…

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:…

Interplay between Sb flux and growth temperature during the formation of GaSb islands on GaP

S. El Kazzi, L. Desplanque, X. Wallart, Y. Wang, P. Ruterana

We investigate the influence of the Sb flux on the growth of GaSb islands on a highly mismatched (001) GaP substrate. Between low and medium Sb flux values, standard kinetics drives the GaSb island formation and their relaxation is progressively favored by 90° misfit dislocations at the GaSb/GaP…

Non-parametric multiple-antenna blind spectrum sensing by predicted eigenvalue threshold

Kais Hassan, Roland Gautier, Iyad Dayoub, Emanuel Radoi, Marion Berbineau

In this paper, we consider the problem of sensing a primary user in a cognitive radio network by employing multiple antennas at the secondary user. Among the many spectrum-sensing methods, the predicted eigenvalue threshold (PET) based method is a promising non-parametric blind method that can…
