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...

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...

A coupler-free differential noise figure measurement technique without noise source on a two-port network analyzer

Yogadissen Andee, Caroline Arnaud, Philippe Seurre, Francois Danneville

This paper presents a measurement technique for the noise figure of differential amplifiers using commercially-available 2-port network analyzers. It is based on the measurement of the noise wave correlation at the output ports of the differential amplifier. A simple measurement setup is used as...

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-...

Impact of clustering at mmW band frequencies

Maria-Teresa Martinez-Ingles, Davy Gaillot, Juan Pascual-Garcia, Jose-Maria Garcia-Pardo, Martine Lienard, Jose-Victor Rodriguez, Leandro Juan-Llacer

In this work different clustering approaches are investigated in the millimeter-wave (mm-W) frequency band from measurements and simulations. Multipath Component (MPC) parameters have been extracted from both measurements and simulations using RiMAX. Following this step, several clustering...
