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...

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-...

Frequency response modeling and optimization of a PIN photodiode based on GaN/InGaN adapted to photodetection at a wavelength of 633 nm

M. El Besseghi, Abdelkader Aissat, Bandar Alshehri, Karim Dogheche, El Hadj Dogheche, Didier Decoster

In this paper, the frequency response calculation and optimization of PIN photodiodes based on GaN/InGaN, suitable for photodetection at the wavelength of 633 nm, are presented. The calculations of the impulse as well as the frequency response are performed using the impulse method. The frequency...

Capillary tube wetting induced by particles: towards armoured bubbles tailoring

Farzam Zoueshtiagh, Michael Baudoin, David Guérin

In this paper, we report on the strongly modified dynamics of a liquid finger pushed inside a capillary tube, when partially wettable particles are lying on the walls. Particles promote the appearance of new regimes and enable the tailored synthesis of bubbles encapsulated in a monolayer of...
