Type I band alignment in GaAs 81 Sb 19 /GaAs core-shell nanowires

Tao Xu, Mengjie Wei, Pierre Capiod, Adrian Díaz Álvarez, Xiang-Lei Han, David Troadec, Jean-Philippe Nys, Maxime Berthe, Isabelle Lefebvre, Gilles Patriarche, S.R. Plissard, Philippe Caroff, Philipp Ebert, B. Grandidier

The composition and band gap of the shell that formed during the growth of axial GaAs/GaAs81Sb19/ GaAs heterostructure nanowires have been investigated by transmission electron microscopy combined with energy dispersion spectroscopy, scanning tunneling spectroscopy, and density functional theory…

Energy Consumption of Networked Embedded Systems

Nadir Cherifi, Gilles Grimaud, Thomas Vantroys, Alexandre Boé

The Web of Things (WoT) defines the idea of addressing and requesting any surrounding connected device through web applications. These devices are for a large part, tiny, wireless and mostly battery-powered. Therefore, energy represents a critical limiting resource for their large scale deployment…

Experimental Analysis and Modelling of Coaxial Transmission Lines with Soft Shield Defects

Hossein Manesh, Abelin Kameni, Florent Loete, Jérôme Genoulaz, Lionel Pichon, Odile Picon

Significant research has focused on the diagnosis of “hard” faults (open and short circuits) in transmission lines, but there has been much less work on “soft” faults resulting from a very small change in line impedance. This research is based on one type of soft fault problems in electrical fault…

Multi-scale pore structure of COx claystone: Towards the prediction of fluid transport

Yang Song, Catherine A. Davy, David Troadec, Anne-Marie Blanchenet, Frédéric Skoczylas, Jean Talandier, Jean-Charles Robinet

We aim to relate the morphology of the pore network of finely porous claystones to their fluid transport properties. By using Focused Ion Beam in combination with Scanning Electron Microscopy (FIB/SEM), we image the pore network of COx claystone from 2D image stacks and as 3D reconstructed volumes…

Laser-ultrasound-based non-destructive testing

Frédéric Faëse, Frédéric Jenot, Mohammadi Ouaftouh, Marc Duquennoy, Mohamed Ourak

Laser-ultrasound-based non-destructive testing (NDT) applications usually use circular or linear thermoelastic sources. This paper studies two more complex sources and presents their specific advantages. The first thermoelastic source is a regular line array, whereas the second one is a chirped…

Probing technique for localized thermal conductivity measurement

K. Ziouche, Z. Bougrioua, P. Lejeune, T. Lasri, Didier Leclercq

A low-cost and non-destructive measurement technique based on the combination of a temperature sensor and a heater integrated in a very sharp tip is proposed for the determination of thermal conductivity of planar materials. The thermal sensor is fabricated by means of microtechnology technique.…

Self-Equilibration of the Diameter of Ga-Catalyzed GaAs Nanowires

V. Dubrovskii, T. Xu, A. Díaz Álvarez, S.R. Plissard, P. Caroff, F. Glas, B. Grandidier

Designing strategies to reach monodispersity in fabrication of semiconductor nanowire ensembles is essential for numerous applications. When Ga-catalyzed GaAs nanowire arrays are grown by molecular beam epitaxy with help of droplet-engineering, we observe a significant narrowing of the diameter…
