Interface thermal behavior in nanomaterials by thermal grating relaxation

Pier Luca Palla, Sonia Zampa, Évelyne Martin, Fabrizio Cleri

We study the relaxation of a thermal grating in multilayer materials with interface thermal resistances. The analytical development allows for the numerical determination of this thermal property in Approach to Equilibrium Molecular Dynamics and suggests an experimental setup for its measurement....

Étude par microscopie à sonde locale des propriétés électriques de monocouches auto-assemblées de molécules photo-commutables sur substrats ferromagnétiques, C-AFM study of photoswitchable Self-Assembled Monolayers on ferromagnetic substrates

Louis Thomas

Ce manuscrit traite du transport à travers des monocouches auto-assemblées (self-assembled monolayers, SAMs) de molécules photoisomérisables greffées sur des matériaux ferromagnétiques (FMs) pour des applications à la frontière de l'électronique moléculaire et de la spintronique. Ces systèmes..., This thesis focuses on electrical transport through self-assembled monolayers (SAMs) of photoisomerisable compounds grafted on ferromagnetic materials (FMs) for applications at the frontier between molecular electronics and spintronics. These systems have been characterized by conductive atomic...

Structures périodiques et désordonnées pour l’absorption des ondes électromagnétiques, Periodic and disordered structures for the absorption of electromagnetics waves

Nicolas Fernez

L’absorption des ondes électromagnétiques est un objectif suscitant beaucoup d’intérêt de nos jours notamment pour les applications en furtivité dans le domaine militaire, mais également dans le domaine civil pour limiter l’exposition aux signaux de communication sans fil et pour préserver l’..., Absorption of electromagnetic power arouses a lot of interest not solely for stealth applications in military domain, but also in civil life to reduce the exposure to wireless communication signals and to preserve the totality of exchanged information. Absorbers designing for low frequency domain...

Sensitivity to Dispersion Forces in First-Principles Modeling of Disordered Chalcogenides

Carlo Massobrio, Évelyne Martin, Ziyad Chaker, Mauro Boero, Assil Bouzid, Sébastien Le Roux, Guido Ori

The inclusion of dispersion (van der Waals, vdW) forces in first-principles modeling of disordered chalcogenides is analyzed and critically discussed in view of their impact on the atomic structure. To this purpose we considered the case of glassy GeTe4. We selected a vdW correction (termed vdWG...

THz-TDS time-trace analysis for the extraction of material and metamaterial parameters

Romain Peretti, Sergey Mitryukovskiy, Kevin Froberger, Aniss Mebarki, Sophie Eliet Eliet-Barois, Mathias Vanwolleghem, Jean-Francois Lampin

We report on a method and an associated open source software, Fit@TDS, working on an average personal computer. The method is based on the fitting of a time-trace data of a terahertz time-domain-spectroscopy system enabling the retrieval of the refractive index of a dielectric sample and the...

Caractérisation hyperfréquence sous pointes de nano-dispositifs : métrologie et instrumentation, On-wafer microwave characterization of nano-devices : metrology and instrumentation

Khadim Daffé

Dans un contexte de développement spectaculaire des nano-objets, il est nécessaire de développer des moyens de caractérisation électrique haute fréquence sous pointes adaptés aux petites échelles. En particulier, deux verrous instrumentaux doivent être levés. D’une part, la principale difficulté..., In the frame of the spectacular development of nano-objects, innovative on-wafer electrical measurement methods must be addressed at the nanoscale. In particular, two main issues have been identified. On one hand, nano-devices exhibit very high dynamic impedance in contrast with conventional...

The Impact of H.264 Non-Desynchronizing Bits on Visual Quality and its Application to Robust Video Decoding

Firouzeh Golaghazadeh, Stephane Coulombe, François-Xavier Coudoux, Patrick Corlay

In this paper, the concept of non-desynchronizing bits (NDBs) is defined in the context of H.264 video as a bit whose inversion does not cause desynchronization at the bitstream level or change the number of decoded macroblocks. We established that, on the whole, NDBs make up about a third (about...
