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…

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…
