Deep structural analysis of novel BGaN material layers grown by MOVPE

S. Gautier, G. Patriarche, T. Moudakir, M. Abid, G. Orsal, K. Pantzas, David Troadec, A. Soltani, L. Largeau, O. Mauguin, A. Ougazzaden

BGaN ternary alloys with 0.7% and 1.7% boron grown on GaN/sapphire template substrates by metalorganic vapour phase epitaxy (MOVPE) have been investigated through HAADF-STEM. At low boron content, 0.7%, no compositional fluctuations were observed with XRD or STEM measurements. Photoluminescence at…

Structural and optical properties of nanodots, nanowires, and multi-quantum wells of III-nitride grown by MOVPE nano-selective area growth

W.H. Goh, G. Patriarche, P.L. Bonanno, S. Gautier, T. Moudakir, M. Abid, G. Orsal, A.A. Sirenko, Z.-H. Cai, A. Martinez, A. Ramdane, L. Le Gratiet, David Troadec, A. Soltani, A. Ougazzaden

Nanodots, nanowires, and semi-polar quantum well structures of GaN-based material have been grown by nano-selective area growth (NSAG). The growth evolution of the nanostructure has been studied. Cross-sectional transmission electron microscopy (TEM) shows that the nanostructures are free of…

Exploit the bandwidth capacities of the perfluorinated graded index polymer optical fiber for multi-services distribution

C. Lethien, Christophe Loyez, Jean-Pierre Vilcot, N. Rolland, P.A. Rolland

The study reported here deals with the exploitation of perfluorinated graded index polymer optical fiber bandwidth to add further services in a home/office network. The fiber properties are exhibited in order to check if perfluorinated graded index plastic optical fiber (PFGI-POF) is suitable to…

High frequency ultrasound, a tool for elastic properties measurement of thin films fabricated on silicon

Pierre Campistron, Julien Carlier, N. Saad, J. Gao, Malika Toubal, L. Dupont, Georges Nassar, Bertrand Nongaillard

The main goal of this work is to develop an ultrasonic high frequency measurement method for the characterization of thin layers. The development of high frequency acoustic transducers for longitudinal waves and shear waves on silicon has made it possible to develop characterization of thin films…

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…

Thickness effect on nanoscale electromechanical activity in Pb(Mg1/3Nb2/3)O3-PbTiO3 thin films studied by piezoresponse force microscopy

A. Ferri, M. Detalle, J.F. Blach, M. Warenghem, Denis Remiens, R. Desfeux

0.7Pb(Mg1/3Nb2/3)O3–0.3PbTiO3 (PMN–PT) ferroelectric thin films with thickness ranging from 28 to 110 nm were sputter deposited onto LaNiO3/SiO2/Si substrates. Optical properties were determined by spectroscopic ellipsometry. We found B = 4.6 and λ0 = 209 nm, which is consistent for all PMN–PT…

Magnetoelectric memory using perpendicular magnetization states and magnetoelastic switching

Nicolas Tiercelin, Yannick Dusch, V.L. Preobrazhensky, Philippe Pernod

We present here a concept of a memory cell called MELRAM based on a magnetic element with giant magnetostriction, embedded in a piezoelectric matrix. Two equilibrium orientations of magnetization are defined by combining uniaxial anisotropy together with a magnetic polarization in the hard axis…
