Acousto-optical tunable transmissive grating beam splitter

Anthony Dieulangard, Jean-Claude Kastelik, Samuel Dupont, Joseph Gazalet

We present a tunable transmissive grating beam splitter for multiple laser line separation based on acousto-optic interaction in tellurium dioxide. Acousto-optic devices are well known for light modulation, frequency shifting, filtration or deflection. For a deflector, the incident light beam is…

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…

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…

Performance analysis of antenna arrays in tunnel environment

M. Lienard, C. Sanchis-Borras, J. Molina-Garcia-Pardo, D. Gaillot, Pierre Laly, Pierre Degauque

Previous works have shown that multiple-input-multiple- output techniques such as space-time block code applied to tunnel environments present better performances than a single-input-single-output transmission, despite the small angular spread of the rays in this environment. Nevertheless, taking…

PbS quantum dots and ZnO nanowires for 3rd generation solar cells

Basma El Zein, El Hadj Dogheche, Enrico Traversa

Semiconductor nanostructures with low dimensions such as quantum dots and nanowires are considered as important building blocks for the third generation solar cells, due to their useful optical and electrical properties. Quantum dots and nanowires hold promising potency to improve the performance…

Approach-to-equilibrium molecular dynamics for thermal conductivies and boundary conductances

Pier Luca Palla, Evelyne Lampin, Pierre-Arnaud Francioso, Fabrizio Cleri

Thermal transport is simulated at the atomic scale by approach-to-equilibrium molecular dynamics simulations (AEMD) [1]. In this method, a hot and a cold regions are delimited, before the approach-to-equilibrium is simulated by releasing the thermal constraint. The temperature difference between…

Elastic field scattered by a resonator in an acoustic metamaterial

Bernard Bonello, Rémi Marchal, Rayisa P. Moiseyenko, Yan Pennec, Bahram Djafari-Rouhani, J. Zhao, Olga Boyko-Kazymyrenko

Locally resonant sonic materials are artificially structured composites designed to exhibit negative effective mass density and/or elastic constants at frequencies below the Bragg band gap, giving rise to one or several forbidden bands in a frequency range where the elastic wavelength is much…

Measurement of the thermal conductivity of polydimethylsiloxane polymer using the three omega method

Nadine Al-Khudary, Pierre-Yves Cresson, Yovan Orlic, Philippe Coquet, Philippe Pernod, T. Lasri

Polydimethylsiloxane (PDMS) has widely appeared in different electronic and medical applications. The knowledge of the thermal properties of PDMS and especially its thermal conductivity is required while processing PDMS to design a particular device. In this paper measurement of the thermal…
