Optically active defects in an InAsP/InP quantum well monolithically grown on SrTiO3(001)

Jinquan Cheng, Thomas Aviles, Ahiram El Akra, C. Bru-Chevallier, Ludovic Largeau, Gilles Patriarche, Philippe Regreny, A. Benamrouche, Y. Robach, Guy Hollinger, Guillaume Saint-Girons

The optical properties of an InAsP/InP quantum well grown on a SrTiO3(001) substrate are analyzed. At 13 K, the photoluminescence yield of the well is comparable to that of a reference well grown on an InP substrate. Increasing the temperature leads to the activation of nonradiative mechanisms for…

Après avoir privilégié la puissance et le confort des véhicules, les constructeurs automobiles, au vu de l’augmentation du nombre d’accidents et de morts sur la route, sont maintenant attentifs à la sécurité. Ceci explique l’introduction de systèmes de sécurité intelligents, basés sur des capteurs…, After privileging mechanical power and comfort of vehicles, automotive operators, considering the constant increase of accidents and deaths along the roads, are now involved in security. This explains the introduction of intelligent security systems, based on sensors giving a perception of the…

Impact of drops on non-wetting biomimetic surfaces

Alain Merlen, Philippe Brunet

We have carried out an experimental study of liquid drop impact on superhydrophobic substrates covered by a carpet of chemically coated nano-wires. The micro-structure of the surface is similar to some biological ones (Lotus leaf for example). In this situation the contact angle can then be…

Process Optimization and Downscaling of a Single Electron Single Dot Memory

Christophe Krzeminski, Xiaohui Tang, Nicolas Reckinger, Vincent Bayot, Emmanuel Dubois

This paper presents the process optimization of a single-electron nanoflash electron memory. Self-aligned single dot memory structures have been fabricated using a wet anisotropic oxidation of a silicon nanowire. One of the main issue was to clarify the process conditions for the dot formation.…
