Hybrid organic-inorganic nanocomposites for terahertz applications

D. Hourlier-Bahloul, Srisaran Venkatachalam, Christophe Boyaval, Guillaume Ducournau, Y. Blum, Jean-Francois Lampin

The TeraHertz (THz) portion corresponds to the part of the electromagnetic spectrum having frequencies ranging from 0.3 to 10 THz. Unlike UV or X-rays, THz photons are not energetic enough to break chemical bonds or to ionize atoms or molecules. These radiations have found widespread applications...

Scanning tunneling microscopy of GaAs/GaAsSb nanowires

Adrian Díaz Álvarez, Pierre Capiod, Maxime Berthe, Tao Xu, Jean-Philippe Nys, Isabelle Lefebvre, Philippe Caroff, Philipp Ebert, B. Grandidier

Understanding surface structure and surface composition is of particular importance for semiconductor nanowire applications, since they might strongly contribute to the electrical, optical and thermal properties of the Nanowires. A prototypical material is GaAs, where polytype inclusions consisting...

Dispersion properties and low infrared optical losses in epitaxial AlN on sapphire substrate in the visible and infrared range

Ali Soltani, Arnaud Stolz, Joël Charrier, Maghnia Mattalah, Jean-Claude Gerbedoen, Hassan Ali Barkad, Vincent Mortet, Michel Rousseau, Nour Eddine Bourzgui, Ali Benmoussa, Jean-Claude de Jaeger

Optical waveguiding properties of a thick wurtzite aluminum nitride highly [002]-textured hetero-epitaxial film on (001) basal plane of sapphire substrate are studied. The physical properties of the film are determined by X-ray diffraction, atomic force microscopy, microRaman, and photocurrent...

Optimized V-shape design of GaN nanodiodes for the generation of Gunn oscillations

J.F. Millithaler, I. Iniguez-De-La-Torre, A. Iniguez-De-La-Torre, T. Gonz Alez, P. Sangaré, Guillaume Ducournau, Christophe Gaquière, J. Mateos

In this work, recent advances in the design of GaN planar Gunn diodes with asymmetric shape, socalled self-switching diodes, are presented. A particular geometry for the nanodiode is proposed, referred as V-shape, where the width of the channel is intentionally increased as approaching the anode....

On the effect of δ-doping in self-switching diodes

Andreas Westlund, Ignacio Iñiguez-De-La-Torre, Per-Åke Nilsson, Tomas González, Javier Mateos, Paul Sangaré, Guillaume Ducournau, Christophe Gaquière, L. Desplanque, Xavier Wallart, Jan Grahn

Lowering the carrier concentration is presented as a way to considerably improve the performance of self-switching diode (SSD) detectors. A physics-based theoretical model was used to derive an expression for the responsivity of SSDs as a function of carrier concentration, mobility, and design...

Effect of polarization switching cycles on the dielectric response and Rayleigh constant in Pb0.4Sr0.6TiO3 thin films

Kui Li, Xianlin Dong, Denis R Émiens, Tao Li, Ying Chen, Genshui Wang

Pb0.4Sr0.6TiO3 thin films with good fatigue endurance were crystallized at low temperature compatible with the current semiconductor technology. The effect of polarization switching cycles on the ferroelectric properties, dielectric response, and Rayleigh constant in thin films were systematically...

Modulation recognition for MIMO relaying broadcast channels with direct link

Wassim Ben Chikha, Iyad Dayoub, Walaa Hamouda, Rabah Attia

In this letter, we investigate the performance of modulation identification based on pattern recognition approach using the decision tree (J48) classifier, for multiple-inputmultipleoutput (MIMO) relaying broadcast channels with direct link (source-to-destination). The proposed system identifies...

On Popularization of Scientific Education In Italy Between 12th And 16th Centuries

Raffaele Pisano, Paolo Bussotti

Mathematics education is also a social phenomenon because it is influenced both by the needs of the labour market and by the basic knowledge of mathematics necessary for every person to be able to face some operations indispensable in the social and economic daily life. Therefore the way in which...
