Comparison of Fe and Si doping of GaN: An EXAFS and Raman study

M. Katsikini, F. Pinakidou, J. Arvanitidis, E.C. Paloura, S. Ves, Ph. Komninou, Z. Bougrioua, E. Iliopoulos, T.D. Moustakas

The effect of Fe and Si doping in GaN grown epitaxially on Al2O3 is studied using Extended X-ray Absorption Fine Structure (EXAFS) and Raman spectroscopies. The EXAFS analysis shows that in GaN samples grown by Molecular Beam Epitaxy (MBE) at 750 °C the Ga–Ga distance is about 0.19% longer than the...

Simultaneous guidance of slow photons and slow acoustic phonons in silicon phoxonic crystal slabs

Vincent Laude, Jean-Charles Beugnot, Sarah Benchabane, Yan Pennec, Bahram Djafari-Rouhani, Nikos Papanikolaou, Jose M. Escalante, Alejandro Martinez

We demonstrate theoretically that photons and acoustic phonons can be simultaneously guided and slowed down in specially designed nanostructures. Phoxonic crystal waveguides presenting simultaneous phononic and photonic band gaps were designed in perforated silicon membranes that can be...

Coating of structured catalytic reactors by plasma assisted polymerization of tetramethyldisiloxane

A. Essakhi, B. Mutel, P. Supiot, A. Lofberg, S. Paul, V. Le Courtois, V. Meille, I. Pitault, E. Bordes-Richard

An original process based on cold plasma assisted polymerization of tetramethyldisiloxane (TMDSO) in the presence of O2 was developed to cover substrates showing various shapes (plate and foam). In the frame of catalytic application, this coating has to act as a bonding layer for the deposition of...

Impulsive Interference Mitigation in Ad Hoc Networks Based on Alpha-Stable Modeling and Particle Filtering

Nouha Jaoua, Emmanuel Duflos, Philippe Vanheeghe, Laurent Clavier, François Septier

In this paper, we tackle the problem of interference mitigation in ad hoc networks. In such context, the multiple access interference (MAI) is known to be of an impulsive nature. Therefore, the conventional Gaussian assumption can not be considered to model this type of interference. Contrariwise,...

Coupling of excitons and defect states in boron-nitride nanostructures

Claudio Attaccalite, M. Bockstedte, A. Marini, A. Rubio, L. Wirtz

The signature of defects in the optical spectra of hexagonal boron nitride (BN) is investigated using many body perturbation theory. A single BN-sheet serves as a model for different layered BN- nanostructures and crystals. In the sheet we embed prototypical defects such as a substitutional...

Growth of antimony-containing heterostructure nanowires by molecular beam epitaxy : crystal phase control, surfaces and interfaces

Philippe Caroff, Tao Xu, Kimberly A. Dick, S.R. Plissard, Thanh Hai Nguyen, B. Grandidier, X. Wallart

Growth of III-V nanowires has now gained some maturity and fundamental understanding of the growth mechanisms has dramatically progressed. However, there are only three families of III-Vs which have been extensively explored: nitrides, arsenides and phosphides. The growth and understanding of...

Conducting interpenetrating polymer network sized to fabricate microactuators

Alexandre Khaldi, Cedric Plesse, Caroline Soyer, Eric Cattan, Frederic Vidal, Christiane Legrand, Dominique Teyssié

Interpenetrating polymer networks can become successful actuators in the field of microsystems providing they are compatible with microtechnologies. In this letter, we report on a material synthesized from poly(3,4-ethylenedioxythiophene) and polytetrahydrofuran/poly(ethylene oxide) and microsized...
