Design and fabrication of uni-travelling carrier (UTC) photodiode based on InxGa1-xN semiconductors

Bandar Alshehri, Karim Dogheche, P.I. Seetoh, J.H. Teng, S.J. Chua, Didier Decoster, El Hadj Dogheche

This work is focused both on InxGa1-xN single-layer and InxGa1-xN/GaN multilayered structures, with high Indium content (x>35%). In this study, InGaN/GaN films are epitaxially grown on sapphire substrates by metalorganic chemical vapor deposition (MOCVD). The microstructure of GaN and InxGa1-xN...

Features of acoustic resonance in iron borate

K.M. Skibinsky, M.B. Strugatsky, S.V. Yagypov, A.I. Yevstafyev, V.L. Preobrazensky, V.N. Bersansky

Acoustic resonance in a weak-ferromagnetic iron borate monocrystal was investigated. It was shown that observed field dependence of positions and magnitudes of the resonance peaks can be explained within framework of the developed theory of magnetic birefringence of sound in the inhomogeneous...

Polarization properties of specular and dense multipath components in a large industrial hall

Isabelle Vin, Davy Gaillot, Emmeric Tanghe, Wout Joseph, Pierre Laly, M. Lienard, Luc Martens

This paper presents a comprehensive analysis of the polarization characteristics of specular and dense multipath components in a large industrial hall, based on frequency-domain channel sounding experiments at 1.3 GHz. The RiMAX maximum-likelihood estimator is used to extract the full-polarimetric...

Graphene nanotransistors for RF charge detection

E. Pallecchi, Q. Wilmart, A.C. Betz, S.H. Jhang, G. Fève, J.M. Berroir, Sylvie Lepilliet, Gilles Dambrine, H. Happy, B. Plaçais

We have studied the static and dynamical properties of a graphene microwave nanotransistor to be used as sensitive fast charge detectors. The channel consists of exfoliated graphene on SiO2 with a 120 nm long, 900-1500 nm wide top-gate deposited on 5 nm AlOx dielectric. The scattering parameters...

Direct path detection algorithm in multiple input single output configuration for transport applications

Kobenan Ignace Kossonou, Yassin El Hillali, Michael Bocquet, Atika Rivenq, Jamal Assaad

This paper introduces a novel technique that exploits cross-correlation properties of near-orthogonal pseudonoise (PN) codes to estimate the time of arrival of the direct path signal for Multiple Input Single Output (MISO) applications. Indeed, multipath are a source of error in the time...

Cascaded Brillouin fibre lasers coupled to unitravelling carrier photodiodes for narrow linewidth terahertz generation

Guillaume Ducournau, Denis Bacquet, P. Szriftgiser, Fabio Pavanello, Emilien Peytavit, Mohamed Zaknoune, Alexandre Beck, Jean-Francois Lampin

Narrow linewidth terahertz (THz) generation using a cascaded Brillouin fibre laser structure and a unitravelling carrier photodiode is investigated. Using two distributed feedback lasers separated by > 1 THz with 1 MHz initial linewidth, the use of the cascaded Brillouin laser greatly increases...

Magneto-transport subband spectroscopy in InAs nanowires

Florian Vigneau, Vladimir Prudkovskiy, Ivan Duchemin, Walter Escoffier, Philippe Caroff, Yann-Michel Niquet, Renaud Leturcq, Michel Goiran, Bertrand Raquet

We report on magnetotransport measurements in InAs nanowires under a large magnetic field (up to 55 T), providing a spectroscopy of the one-dimensional electronic band structure. Large modulations of the conductance mediated by a control of the Fermi energy reveal the Landau fragmentation, carrying...
