La sismique réflexion haute résolution, outil complémentaire du radar géologique pour la reconnaissance des souches superficielles

Bogdan Piwakowski, C. Leonard, Isam Shahrour

Cet article présente une application réussie de l'imagerie sismique réflexion haute résolution (SHR) pour la reconnaissance de couches superficielles. Des progrès récents dans ce domaine ont été accomplis en ce qui concerne les systèmes de mesure, le traitement des signaux et les techniques d…

Detection of chemical damage in concrete using ultrasound

S. Ould Naffa, Marc Goueygou, Bogdan Piwakowski, François Buyle-Bodin

This research deals with a non-destructive method for characterizing the degraded cover of concrete structures using high-frequency ultrasound (0.5–1 MHz). Although such a frequency range is unusual in civil engineering, it is well suited to the kind of defect to be detected, as it corresponds to a…

Assessment of broadhand ultrasonic attenuation measurements in inhomogeneous media

Marc Goueygou, Bogdan Piwakowski, S. Ould Naffa, François Buyle-Bodin

In this paper, we address the problem of evaluating the acoustic attenuation of “difficult” media, i.e. highly attenuating and scattering media. In a broadband, through transmission setup, the signals acquired from such media are characterized by a poor signal-to-noise ratio. Therefore, an accurate…

A combined RHEED and photoemission comparison of the GaP and InP (001) (2x4) surface reconstructions

X. Wallart

In this work, we compare the (2×4) reconstructions of GaP and InP(0 0 1) surfaces. Two different (2×4) reconstructions are detected by reflection high energy electron diffraction for both materials. Photoemission experiments reveal that the high temperature one is cation-rich whereas the low…

Long dephasing time and high temperature conductance fluctuations in open InGaAs quantum dot

Benoit Hackens, François Delfosse, Sébastien Faniel, Cédric Gustin, Hervé Boutry, X. Wallart, S. Bollaert, A. Cappy, Vincent Bayot

We measure the electron phase-coherence time τφ up to 18 K using universal fluctuations in the low-temperature magnetoconductance of an open InGaAs quantum dot. The temperature dependence of τφ is quantitatively consistent with the two-dimensional model of electron-electron interactions in…
