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…

Study of an hybridization gap in a one dimensional piezoelectric phononic crystal

Sid Ali Mansoura, Bruno Morvan, Pierre Maréchal, Anne-Christine Hladky, Bertrand Dubus

A one dimensional Phononic Crystals (PC) composed of a periodic stack including piezoelectric plates is studied. When the size of the pattern is a multiple of the wavelength, Bragg gaps appear based on interference mechanisms. In addition to this property, it is shown in this paper that the use of…

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-…
