Adaptive Joint Semi-blind Estimation of CFO and Channel for OFDM Systems

Mokhtar Besseghier, Ahmed Bouzidi Djebbar, Iyad Dayoub

The large number of subcarriers, used in OFDM systems, increases the sensivity to frequency offset which results from a Doppler shift, due to mobile movement, as well as from a mismatch between the carrier frequencies at the transmitter and receiver. The problem of channel estimation in a practical...

Properties of boron-doped epitaxial diamond layers grown on (110) oriented single crystal substrates

Vincent Mortet, Julien Pernot, François Jomard, Ali Soltani, Z. Remes, Julien Barjon, J. d'Haen, Ken Haenen

Boron doped diamond layers have been grown on (110) single crystal diamond substrates with B/C ratios up to 20 ppm in the gas phase. The surface of the diamond layers observed by scanning electron microscopy consists of (100) and (113) micro-facets. Fourier Transform Photocurrent Spectroscopy...

Formation of quantum dots in the potential fluctuations of InGaAs heterostructures probed by scanning gate microscopy

Peng Liu, Frederico Martins, Benoit Hackens, L. Desplanque, Xavier Wallart, Marco Pala, Serge Huant, Vincent Bayot, Hermann Sellier

The disordered potential landscape in an InGaAs/InAlAs two-dimensional electron gas patterned into narrow wires is investigated by means of scanning gate microscopy. It is found that scanning a negatively charged tip above particular sites of the wires produces conductance oscillations that are...

Influence of Molecular Organization on the Electrical Characteristics of π‑Conjugated Self-Assembled Monolayers

Xavier Lefèvre, Fabrice Moggia, Olivier Segut, Yu-Pu Lin, Younal Ksari, Grégory Delafosse, Kacem Smaali, David Guérin, Vincent Derycke, Dominique Vuillaume, Stéphane Lenfant, Lionel Patrone, Bruno Jousselme

Two new thiol compounds with σ−π−σ structure were synthesized and self-assembled on gold substrates. The morphology and the structural characterization of SAMs assessed by infrared spectroscopy, contact angle, XPS, electrochemistry and scanning tunneling microscopy (STM) show the formation of...

Inhibition of type 1 fimbriae-mediated Escherichia coli adhesion and biofilm formation by trimeric cluster thiomannosides conjugated to diamond nanoparticles.

Manakamana Khanal, Fanny Larsonneur, Victoriia Raks, Alexandre Barras, Jean-Sebastien Baumann, Fernando Ariel Martin, Rabah Boukherroub, Jean-Marc Ghigo, Carmen Ortiz Mellet, Vladimir Zaitsev, Jose M. Garcia Fernandez, Christophe Beloin, Aloysius Siriwardena, Sabine Szunerits

Recent advances in nanotechnology have seen the development of a number of microbiocidal and/or anti-adhesive nanoparticles displaying activity against biofilms. In this work, trimeric thiomannoside clusters conjugated to nanodiamond particles (ND) were targeted for investigation. NDs have...

Surface-Induced Optimal Packing of Two-Dimensional Molecular Networks

Guillaume Copie, Fabrizio Cleri, Younes Makoudi, Christophe Krzeminski, Maxime Berthe, Frederic Cherioux, Frank Palmino, B. Grandidier

High-density packing in organic crystals is usually associated with an increase of the coordination between molecules. Such a concept is not necessarily extended to two-dimensional molecular networks self-assembled on a solid surface, for which we demonstrate the key role of the surface in inducing...

Non-Arrhenius conduction due to the interface-trap-induced disorder in X-doped amorphous In-X-Zn oxides thin-film transistors

Mohammed Benwadih, Jan Chroboczek, Gérard Ghibaudo, Romain Coppard, Dominique Vuillaume

Thin film transistors, with channels composed of In-X-Zn oxides, IXZO, with X dopants: Ga, Sb, Be, Mg, Ag, Ca, Al, Ni, and Cu, were fabricated and their I-V characteristics were taken at selected temperatures in the 77 K < T < 300 K range. The low field mobility, μ, and the interface defect...
