Electron-phonon coupling and optical transitions for indirect-gap semiconductor nanocrystals

Christophe Delerue, Michel Lannoo, Guy Allan

We show that it is possible to perform full microscopic calculations of the phonon-assisted and no-phonon radiative transitions in silicon nanocrystals. These are based on a tight-binding Hamiltonian for the electron and electron-phonon part together with a valence force-field model for phonons. We…

High Performance Heterostructure Barrier Varactors

Didier Lippens, Xavier Mélique, S. Arscott, Thibaut David, V. Duez, Jorge Carbonell, Patrick Mounaix, Olivier Vanbésien, Francis Mollot

We report on the physics, fabrication technology and characterisation of high performance Heterostructure Barrier Varactors diodes. State-of-the art results in terms of capacitance ratios of up to 10:1 and voltage handling have recently been published for InP-and GaAs-based devices with a typical…

Millimeter-wave passive imaging system for survey and obstacle detection in ITS

A. Chams Eddine, Markus Klingler, Marc Heddebaut, Bertrand Bocquet, A. Cappy, Paul-Alain Rolland

There is a recognized need to develop improved systems for survey and obstacle detection offering characteristics such as day, night and adverse weather capabilities, acceptable operating range and adequate spatial resolution. Passive infrared (IR) systems can perform well at night. They are also…

Contribution à l’optimisation du contrôle santé intégré par ondes de Lamb : application à la surveillance de structures aéronautiques, Optimization of Lamb wave based health monitoring systems for aeronautical structure inspection

Sébastien Grondel

Ce travail est consacré à l'étude et à la mise au point d'un système de surveillance embarqué destiné au contrôle santé de structures aéronautiques. Le système choisi pour réaliser ce « contrôle santé intégré » repose, d'une part, sur l'excitation et la réception d'ondes de…, This work is devoted to the study and the development of an health monitoring system assigned to aircraft applications. The chosen health monitoring system is based first on the excitation and reception of Lamb waves along the structure and secondly on a continuous monitoring with the same…
