Subterahertz hypersound attenuation in silica glass studied via picosecond acoustics

Simon Ayrinhac, Marie Foret, Arnaud Devos, Benoit Ruffle, Eric Courtens, René Vacher

We report picosecond acoustic measurements in silica-glass films grown by wet thermal oxidation on a (111) silicon substrate. The longitudinal acoustic phonons are observed over the range from 150 to 300 GHz using an infrared pump and a second harmonic blue probe. The transducer is an aluminum thin…

Above 600 mS/mm transconductance with 2.3 A/mm drain current density AlN/GaN high electron mobility transistors grown on silicon

F Medjdoub, Malek Zegaoui, Nicolas Waldhoff, B. Grimbert, N. Rolland, Paul-Alain Rolland

AlN/GaN high-electron-mobility transistors (HEMTs) capped with an in-situ grown SiN have been successfully developed on 100mm Si substrates. A unique combination of maximum output current density exceeding 2A/mm and a record extrinsic transconductance above 600 mS/mm has been reached, which is well…

Mechanical characterization of aluminium nanofilms

Gregory Guisbiers, Etienne Herth, L. Buchaillot

The mechanical properties (Young’s modulus, hardness, wear resistance) of aluminium nanofilms on silicon substrate are studied. Size effect on these mechanical properties are exhibited. Young’s modulus, hardness and wear resistance increases when the thickness is reduced. Experimental…
