Large-signal modeling up to W-band of AlGaN/GaN based high-electron-mobility transistors

Adrien Cutivet, Philippe Altuntas, N. Defrance, Etienne Okada, Vanessa Avramovic, Marie Lesecq, Virginie Hoel, Jean-Claude de Jaeger, F. Boone, Maher, Hassan

This paper reports on the development of a thermo-electrical non-linear model for sub-100 nm gate length AR:aN/GaN High-Electron-Mobility Transistors (HEMT) grown on silicon (111) substrate by Molecular Beam Epitaxy (MBE). The presented model benefits from the innovative implementations of a sub-...

Tunability of a One-Dimensional Elastic/Piezoelectric Phononic Crystal Using External Capacitances

S. Degraeve, C. Granger, Bertrand Dubus, Jerome O. Vasseur, M. Pham Thi, Anne-Christine Hladky

A superlattice made of alternate rods constituted of piezoelectric ceramic and elastic material is shown, theoretically and experimentally, to exhibit wide Bragg band gaps. The width of these stop bands is affected not only by the elastic impedance ratio between the constituent materials but also...

Role of compositional fluctuations and their suppression on the strain and luminescence of InGaN alloys

Konstantinos Pantzas, Gilles Patriarche, David Troadec, Mathieu Kociak, Nikolay Cherkashin, Martin Hÿtch, Julien Barjon, Christian Tanguy, Thomas Rivera, Sundaram Suresh, Abdallah Ougazzaden

Advanced electron microscopy techniques are combined for the first time to measure the composition, strain, and optical luminescence, of InGaN/GaN multi-layered structures down to the nanometer scale. Compositional fluctuations observed in InGaN epilayers are suppressed in these multi-layered...

High density terahertz frequency comb produced by coherent synchrotron radiation

S Tammaro, Olivier Pirali, P Roy, Jean-Francois Lampin, Guillaume Ducournau, Arnaud Cuisset, Francis Hindle, Gaël Mouret

Frequency combs have enabled significant progress in frequency metrology and high-resolution spectroscopy extending the achievable resolution while increasing the signal-to-noise ratio. In its coherent mode, synchrotron radiation is accepted to provide an intense terahertz continuum covering a wide...

Experimental analysis of Zigbee RF signal performance for railway application: Study on a laboratory reduced scale train

Sara Iben Jellal, O. Cohin, S. Baranowski, Ulrich Biaou, Michael Bocquet, Atika Rivenq

Due to its cost and power performance, Zigbee is widely used and can be applied to railway systems. This paper deals with the performance of a Zigbee (IEEE.802.15.4) RF signal, according to several criteria; this analysis is based on an experimental approach and specially on power measurements in...
