From semiconductor nanocrystals to artificial graphene and topological insulator

Efterpi Kalesaki, Christophe Delerue, Cristiane Morais Smith, Wouter Beugeling, Guy Allan, Daniel Vanmaekelbergh

Recent advancements in colloidal chemistry indicate that two-dimensional single-crystalline sheets of semiconductors forming a honeycomb lattice can be synthesized from semiconductor nanocrystals [1]. We perform atomistic tight-binding calculations of the band structure of CdSe sheets with such a…

Theory of self-assembled nanoparticle networks as logic building blocks

Fabrizio Cleri, Sergio Carrillo, Christophe Krzeminski

Recently, self-assembled networks of functionalized nano particles (NPSAN) were proposed as a prototype of innovative devices [1], with switchable NP-NP links. Thanks to the chemical properties of the surface molecules, these would ultimately show memristive behaviour, as building blocks of a…

Electro-optic and converse piezoelectric coefficients of epitaxial thin films : GaN grown on Si, and (Sr,Ba)Nb2O6 (SBN) grown on Pt coated MgO (poster)

Mireille Cuniot-Ponsard, Irma Saraswati, Suk-Min Ko, Mathieu Halbwax, Yong-Hoon Cho, El Hadj Dogheche

We report the first measurement of the (r13, r33) Pockels electro-optic coefficients in a SBN thin film and in a GaN thin film grown on silicon. The converse-piezoelectric and electro-absorptive coefficients are simultaneously determined.

1900 V, 1.6 mΩ cm2 AlN/GaN-on-Si power devices realized by local substrate removal

Nicolas Herbecq, Isabelle Roch-Jeune, Nathalie Rolland, Domenica Visalli, Joff Derluyn, Stefan Degroote, Marianne Germain, F Medjdoub

We demonstrate a high-voltage low on-resistance AlN/GaN/AlGaN double heterostructure grown by metal-organic chemical vapor deposition on a silicon (111) substrate using a total buffer thickness of less than 2 μm. A fully scalable local substrate removal technique was developed to dramatically…

Microscopie champ proche aux fréquences térahertz

Gabriel Moreno

Ce travail de thèse porte sur l'étude et sur l'adaptation de la microscopie champ proche (s-SNOM) dans les bandes de fréquences moyen-infrarouge (3-15 μm) et terahertz (100 μm - 1 mm). Nous présentons les principales caractéristiques de cette technique de microscopie. Pour cela, une sonde…

Distributional upper bound on the interference in spatial wireless multiuser ultrawideband communication systems

Gareth W. Peters, Ido Nevat, Laurent Clavier, François Septier

We develop a novel distributional upper bound on the interference created in an ultra-wideband wireless communication systems under two general assumptions: the first is that there is an unknown number of interferers who are distributed according to a homogeneous Poisson point process randomly in…

Influence of processing gases on the properties of cold atmospheric plasma SiOxCy coatings

H. Hamze, Maude Jimenez, D. Deresmes, Arnaud Beaurain, Nicolas Nuns, Michel Traisnel

Thin layers of SiOxCy (y = 4−x and 3 ≤ x ≤ 4) were applied using a cold atmospheric plasma torch on glass substrates. The aim was to investigate using Atomic Force Microscopy (AFM), X-ray photoelectron spectroscopy (XPS) and time-of-flight secondary ion mass spectrometry (Tof-Sims) the influence of…

Biostimulation as an attractive technique to reduce phenanthrene toxicity for meiofauna and bacteria in lagoon sediment

Haithem Louati, O.B. Said, A. Soltani, P. Got, Cristiana Cravo-Laureau, Robert Duran, P. Aissa, O. Pringault, E. Mahmoudi

A microcosm experiment was setup to examine (1) the effect of phenanthrene contamination on meiofauna and bacteria communities and (2) the effects of different bioremediation strategies on phenanthrene degradation and on the community structure of free-living marine nematodes. Sediments from…
