Optical properties of aluminum nitride thin films grown by direct-current magnetron sputtering close to epitaxy

Arnaud Stolz, Ali Soltani, Bassam Abdallah, Joël Charrier, D. Deresmes, Pierre-Yves Jouan, Mohamed Abdou Djouadi, El Hadj Dogheche, Jean-Claude de Jaeger

Low-temperature Aluminum Nitride (AlN) thin films with a thickness of 3 μm were deposited by Direct-Current magnetron sputtering on sapphire substrate. They present optical properties similar to those of epitaxially grown films. Different characterization methods such as X-Ray Diffraction,...

Phase transformation of PbSe/CdSe nanocrystals from core-shell to Janus structure studied by photoemission spectroscopy

Justin Habinshuti, Pierre Capiod, T.H. Nguyen, Y. Justo, F.J. Avila, M.C. Asensio, F. Bournel, J.J. Gallet, I. Vobornik, J. Fujii, A. Addad, K. Lambert, Jean-Philippe Nys, Yannick Lambert, Z. Hens, A. Osherov, Y. Golan, O. Robbe, S. Turrell, B. Grandidier

Photoelectron spectroscopic measurements have been performed, with synchrotron radiation on PbSe/CdSe heteronanocrystals that initially consist of core-shell structures. The study of the chemical states of the main elements in the nanocrystals shows a reproducible and progressive change in the...

Clipping demapper for LDPC decoding in impulsive channel

Hassen Benmaad, Alban Goupil, Laurent Clavier, Guillaume Gelle

This paper deals with the performance of Low-Density Parity-Check codes in impulsive interference modeled by α-stable random variables. In case of α-stable noise, the optimal inputs of the belief propagation decoder are complex to obtain. We propose to use the simple clipping approach that reduces...

Washcoating of cordierite honeycomb with Ce–Zr–Mn mixed oxides for VOC catalytic oxidation

S. Azalim, Rachid Brahmi, Mahfoud Agunaou, Arnaud Beaurain, Jean-Marc Giraudon, Jean‐françois Lamonier

The application of monolithic catalysts to the VOC removal is a crucial issue for practical applications in order to minimize the pressure drop in the reactor. In this study, cordierite monoliths coated with Mn, Ce and Zr elements were synthesized, characterized and tested in n-butanol oxidation....
