160W InAlN/GaN HEMTs amplifier at 2 GHz with optimized thermal management

Stéphane Piotrowicz, Olivier Jardel, Jean-Claude Jacquet, D. Lancereau, Raphaël Aubry, Erwan Morvan, Nicolas Sarazin, Jérémy Dufraisse, Charu Dua, Mourad Oualli, Eric Chartier, Marie-Antoinette Di Forte-Poisson, Christophe Gaquière, Sylvain Laurent Delage

We report on the realization and measurements of InAlN/GaN HEMTs on SiC substrate. At device level, load-pull power measurements were performed at 2 GHz on 2.2mm devices in CW mode. An output power of 10.5W (40.2dBm) with a PAE of 53% were reached. Then, an amplifier was realized using 36mm power…

Effect of phonon confinement on the dispersion relation and heat capacity in nanoscale Si membranes

J. Cuffe, E. Chávez, A. Shchepetov, P.O. Chapuis, E.H. El Boudouti, F. Alzina, Yan Pennec, Bahram Djafari-Rouhani, M. Prunnila, J. Ahopelto, C.M. Sotomayor Torres

The effect of confinement on the acoustic phonon dispersion relation and heat capacity in free-standing silicon membranes is investigated, with thickness values down ∼ 8 nm. The discrete phonon branches are observed by angle-resolved inelastic light scattering spectroscopy. The fundamental flexural…
