Thermal characterization of MBE-grown GaN/AlGaN/GaN device on single crystalline diamond

J. Kuzmik, S. Bychikhin, D. Pogany, E. Pichonat, O. Lancry, Christophe Gaquière, G. Tsiakatouras, G. Deligeorgis, A. Georgakilas

Self-heating effects in a molecular beam epitaxy-grown GaN/AlGaN/GaN structure on a single crystalline diamond is investigated. A transient interferometric method, in combination with a three dimensional model, is used to describe a pulsed operation of a transistor-like heater, and a micro-Raman…

Demonstration of low leakage current and high polarization in ultrathin AlN/GaN high electron mobility transistors grown on silicon substrate

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

High quality AlN/GaN heterostructures grown on silicon substrate are demonstrated. It is found that high carrier concentration can be achieved whereas circular diodes showed a low leakage current up to 200 V reverse bias. 200 nm gate length AlN/GaN transistors exhibited a drain current density of 1…

Dielectric dispersion of BaSrTiO3 thin film from centimeter to submillimeter wavelengths

Grégory Houzet, Karine Blary, Sylvie Lepilliet, Didier Lippens, Ludovic Burgnies, Gabriel Vélu, Jean-Claude Carru, Edwin Nguema Agnandji, Patrick Mounaix

The dielectric dispersion of ferroelectric BaxSr1-xTiO3 (BST) thin film in a paraelectric phase was characterized from centimeter to submillimeter wavelengths. To this aim, interdigitated capacitors were patterned on a micrometer scale onto a BST layer with a barium concentration of 0.5 and were…

Highly coherent terahertz wave generation with a dual-frequency Brillouin fiber laser and a 1.55 μm photomixer

Guillaume Ducournau, P. Szriftgiser, Tahsin Akalin, Alexandre Beck, Denis Bacquet, Emilien Peytavit, Jean-Francois Lampin

Thanks to a portable dual-frequency Brillouin fiber laser and a 1.55 μm photomixer, we report the generation of a highly coherent kilohertz level submillimeter wave emission. Low-cost telecommunications components are used to achieve very simple source architecture. The photomixer is composed of a…

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…
