Surface acoustic wave characterization of optical sol-gel thin layers

Dame Fall, François Compoint, Marc Duquennoy, Hervé Piombini, Mohammadi Ouaftouh, Frédéric Jenot, Bogdan Piwakowski, Philippe Belleville, Chrystel Ambard

Controlling the thin film deposition and mechanical properties of materials is a major challenge in several fields of application. We are more particularly interested in the characterization of optical thin layers produced using sol-gel processes to reduce laser-induced damage. The mechanical…

First power performance demonstration of flexible AlGaN/GaN high electron mobility transistor

Sarra Mhedhbi, Marie Lesecq, Philippe Altuntas, N. Defrance, Etienne Okada, Yvon Cordier, Benjamin Damilano, Gema Tabares Jimenez, Abel Ebongue, Virginie Hoel

This letter reports on the first demonstration of microwave power performance at 10 GHz on flexible AlGaN/GaN high-electron-mobility transistor (HEMT). A maximum dc current density of 620 mA/mm at V-GS = 0 V and a peak extrinsic transconductance of 293 mS/mm are obtained for a 2 x 50 x 0.1 mu m(2)…

Microwave and millimeter wave properties of vertically-aligned single wall carbon nanotubes films

Kamel Haddadi, C. Tripon-Canseliet, Q. Hivin, Guillaume Ducournau, E. Teo, P. Coquet, B. K. Tay, Sylvie Lepilliet, Vanessa Avramovic, J. Chazelas, Didier Decoster

We present the experimental determination of the complex permittivity of vertically aligned single wall carbon nanotubes (SWCNTs) films grown on quartz substrates in the microwave regime from 10 MHz up to 67 GHz, with the electrical field perpendicular to the main axis of the carbon nanotubes (CNTs…

Influence of Doping and Tunneling Interface Stoichiometry on n+In 0.5 Ga 0.5 As/p+GaAs 0.5 Sb 0.5 Esaki Diode Behavior

Salim El Kazzi, A Alireza, Caio Cesar Mendes Bordallo, Quentin Smets, Ludovic Desplanque, Xavier Wallart, Olivier Richard, Bastien Douhard, Anne Verhulst, Nadine Collaert, Clement Merckling, Marc Heyns, Aaron Thean

In this work, we study the influence of molecular beam epitaxy (MBE) growth parameters on the behavior of a staggered band gap n+In 0.5 Ga 0.5 As/p+GaAs 0.5 Sb 0.5 Esaki diodes. We first first show that a careful doping is required to avoid any crystal defects. Then the influence of the doping…
