Visualisation de l'écoulement autour d'une aile d'insecte artificielle

Thomas Vanneste, Jean-Paul Bourez, Jean-Bernard Paquet, Sébastien Grondel, Eric Cattan

Le projet d'insecte artificiel IN-ART vise à la réalisation d'un nano-drone à ailes vibrantes de la taille d'un insecte en s'appuyant sur le biomimétisme pour reproduire ses battements d'ailes. Les prototypes, réalisés à l'aide des techniques de fabrication...

Spin-dependent photoelectron tunneling from GaAs into magnetic cobalt

D. Vu, H. Jurca, F. Maroun, P. Allongue, N. Tournerie, A. Rowe, D. Paget, S. Arscott, Emilien Peytavit

The spin dependence of the photoelectron tunnel current from free standing GaAs films into outof-plane magnetized Cobalt films is demonstrated. The measured spin asymmetry (A) resulting from a change in light helicity, reaches ±6% around zero applied tunnel bias and drops to ±2% at a bias of -1.6 V...

Low-noise microwave performance of AlN/GaN HEMTs grown on silicon substrate

F Medjdoub, Nicolas Waldhoff, Malek Zegaoui, B. Grimbert, N. Rolland, Paul-Alain Rolland

Microwave noise performance of state-of-the-art AlN/GaN high-electron-mobility transistors (HEMTs) grown on 100-mm Si substrate has been investigated. DC and RF measurements show the outstanding potential of this structure for high-power millimeter-wave (mmW) applications. A maximum output current...

Effects of AlGaN back barrier on AlN/GaN-on-silicon high-electron-mobility transistors

F Medjdoub, Malek Zegaoui, B. Grimbert, N. Rolland, Paul-Alain Rolland

In this work, the effects of an AlGaN back barrier in the dc and RF performances of AlN/GaN high-electron-mobility transistors (HEMTs) grown on 100 mm Si substrates have been investigated. It is shown that the outstanding dc performance in highly scaled AlN/GaN-on-Si HEMTs can be fully preserved...

Optimization of ohmic contact and adhesion on polysilicon in MEMS–NEMS wet etching process

Etienne Herth, Emmanuelle Algré, Bernard Legrand, Lionel Buchaillot

This paper presents the optimization of polysilicon doping and metallization to form ohmic contact with etching resistance. Indeed, polysilicon doped by ion implantation and ohmic contacts are an important and interesting part of integrated circuit technology or MEMS and NEMS. LPCVD-polysilicon...
