Improved AlGaN/GaN high electron mobility transistor using AlN interlayers

A. Jimenez, Z. Bougrioua, J. Tirado, A. Braña, E. Calleja, E. Munoz, I. Moerman

This work reports on the effects of AlN interlayers embedded into the GaN semi-insulating buffer of AlGaN/GaN high electron mobility transistors, in comparison with standard heterostructures without AlN interlayers. Detailed optical and structural characterization data are presented, along with…

Molecular rectifying diodes from self-assembly on silicon

Stéphane Lenfant, Christophe Krzeminski, Christophe Delerue, Guy Allan, Dominique Vuillaume

We demonstrate a molecular rectifying junction made from a sequential self-assembly on silicon. The device structure consists of only one conjugated (p) group and an alkyl spacer chain. We obtain rectification ratios up to 37 and threshold voltages for rectification between -0.3V and -0.9V. We show…

Impulsive noise on indoor power lines: characterization and mitigation of its effect on PLC systems

Virginie Degardin, M. Lienard, Pierre Degauque, A. Zeddam, F. Gauthier

Intensive measurements of impulsive noise have been carried out on indoor power lines. From this approach, various types of transients are classified and a stochastic noise model is deduced from the statistical analysis of their main characteristics. A power line communication, based on an OFDM…

AlGaN/GaN HEMTS: material, processing, and characterization

F. Calle, T. Palacios, E. Monroy, J. Grajal, M. Verdu, Zahia Bougrioua, Ingrid Moerman

The growth of AlGaN/GaN high electron mobility transistor (HEMT) structures on sapphire by metal organic vapor phase epitaxy (MOVPE) is described, with special emphasis on procedures to reduce dislocation density. All the processing steps involved in the fabrication of nitride-based HEMTs have been…

Directional photon transfer between two wires

L. Dobrzynski, Abdellatif Akjouj, Bahram Djafari-Rouhani, Jerome O. Vasseur, Mohamed Bouazaoui, Jean-Pierre Vilcot, Arnaud Beaurain, Stefan Mc Murtry

The directional transfer of a single photon from one wire to another, leaving all other neighbor states unaffected, is of great importance. We present a simple coupling structure that makes such transfer possible, for any given photon wavelength and linewidth. We give closed-form expressions for…

Optoelectronic components and integrated circuits including up and down conversion techniques and hybrid integration technology

Didier Decoster, Samuel Dupont, V. Magnin

Microwave optical links can be considered as basic bricks for some emerging system applications such as optically supplied microwave antennas. Emitters, optical switching matrices, high speed photodetectors and specific components for up or down conversion, are generic devices or functions for…
