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…

Vortex state in thin films of multicomponent ferroelectrics

Laurent Baudry, Anaïs Sené, Igor A. Luk'Yanchuk, Laurent Lahoche

The distribution of polarization in thin film of multicomponent weak anisotropic ferroelectric under application of an axially symmetric electric field induced by circular electrodes is studied. We demonstrate that above a certain critical field the instability towards abrupt formation of…

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…

Classification de poudres laitières selon leur pouvoir de solvatation estimé par méthode acoustique

Bruno Richard, Malika Toubal, Jean-François Le Page, Georges Nassar, Edouard Radziszewski, Bertrand Nongaillard, Pascal Debreyne, Romain Jeantet, Pierre Schuck, Guillaume Delaplace

L'objectif de ce travail est de valider l’aptitude d’un test non invasif ultrasonore à caractériser la réhydratation (cinétique, mécanisme) de poudres de protéines laitières. Le test consiste à générer une onde ultrasonore et à observer sa transmission à travers la suspension solide/liquide…
