Thermal behavior analysis of GaN based epi-material on different substrates by means of a physical-thermal model

Xing Tang, Michel Rousseau, N. Defrance, Virginie Hoel, A. Soltani, R. Langer, Jean-Claude de Jaeger

For gallium nitride (GaN) based microwave power devices, the thermal behavior due to the self-heating effect constitutes a main limitation because the power dissipation is very high. For this study, a predictive physical-thermalmodel has been developed to analyze the physical and thermal phenomena…

Ultrasonic and acoustic investigation of cheese matrix at the beginning and the end of ripening period

Georges Nassar, Fabrice Lefebvre, A. Skaf, Julien Carlier, Bertrand Nongaillard, Y. Noel

In this paper, a low frequency, dry contact, ultrasonic technique devoted to the study and characterization of cheeses at the beginning and the end of ripening period is investigated. For compact or weakly opened matrix found in the early step of cheese making, ultrasonic velocity is indicated to…

Two-terminal carbon nanotube programmable devices for adaptive architectures

Guillaume Agnus, Weisheng Zhao, Vincent Derycke, Arianna Filoramo, Y. Lhuillier, S. Lenfant, D. Vuillaume, C. Gamrat, J.P. Bourgoin

Carbon nanotube field-effect transistors functionalized with photoconducting polymer act as very efficient and non-volatile two-terminal programmable devices (see figure). Their optoelectronic programmability allows compensating for the critical issue of variability among as-built devices in…

Development of Time-resolved UV Micro-Raman Spectroscopy to measure temperature in AlGaN/GaN HEMTs

Ophélie Lancry, Emmanuelle Pichonat, Julien Réhault, Myriam Moreau, Raphaël Aubry, Christophe Gaquière

We report on the development of Time-resolved Ultraviolet Micro-Raman Scattering to measure transient self-heating effects in semiconductor devices. Temperature measurements are performed on AlGaN/GaN High-electron-mobility transistors (HEMTs) grown on SiC substrate. Ultraviolet excitation probes…

Calculs de champs acoustiques à l'harmonique 2 par décomposition en faisceaux gaussiens

François Vander Meulen, Lionel Haumesser, Jérôme Fortineau, Olivier Bou Matar

Dans le cadre de l'approximation quasi-linéaire, une solution de l'équation KZK peut être obtenue par la méthode des approximations successives qui, dans ce cas,peut être obtenue par la convolution de la fonction source et d'une fonction de Green de forme gaussienne. Wen et Breazeale…

Experimental and numerical investigation of the impact of pulse duration on supercontinuum generation in a photonic crystal fiber

Marco Andreana, Anne Bertrand, Y. Hernandez, Philippe Leproux, Vincent Couderc, S. Hilaire, Guillaume Huss, D. Giannone, Alessandro Tonello, Alexis Labruyère

We present an experimental and numerical study of supercontinuum (SC) generation in a photonic-crystal fiber pumped by optical pulses with constant peak power and adjustable duration, in the range from 185 ps to 1.81 ns.
