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…

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-…

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…
