Monte Carlo modeling of carrier-carrier scattering in semiconductors with nonparabolic bands

Olivier Bonno, Jean-Luc Thobel

An efficient algorithm to account for nonparabolicity in carrier-carrier scattering in an ensemble Monte Carlo simulator is proposed. The major difficulty of modeling intercarrier scattering in semiconductors with nonparabolic bands arises from the two particle momentum and energy conservation laws…

Modeling a surface-mounted Lamb wave emission-reception system : applications to structural health monitoring

Emmanuel Moulin, Sébastien Grondel, Jamal Assaad, Laurent Duquenne

The work described in this paper is intended to present a simple and efficient way of modeling a full Lamb wave emission and reception system. The emitter behavior and the Lamb wave generation are predicted using a two-dimensional (2D) hybrid finite element–normal mode expansion model. Then the…

Structural health monitoring using cross-correlation of an ambient noise field

Najib Abou Leyla, Emmanuel Moulin, Jamal Assaad, Sébastien Grondel, Pascal Poussot

Theoretical and experimental studies in underwater acoustic, seismology and more recently ultrasonic have demonstrated that an estimate of the Time Domain Green Function (TDGF) between two receivers could be obtained from the cross-correlation of a diffuse acoustic noise field of these two…

Investigation on the emission wavelength of GaInNAs/GaAs strained compressive quantum wells on GaAs substrates

Abdelkader Aissat, Said Nacer, Messaoud Bensebti, Jean-Pierre Vilcot

In this paper, we study the effect of the incorporation of nitrogen in strained GaInAs quantum well structures. We evaluate the influence of nitrogen on the conduction band energy by using the band anticrossing model. The incorporation of nitrogen appears to decrease the bandgap energy and increase…

Nonquasi-static large-signal model of GaN FETs through an equivalent voltage approach

Alberto Santarelli, Valeria Di Giacomo, Antonio Raffo, Fabio Filicori, Giorgio Vannini, Raphaël Aubry, Christophe Gaquière

A new empirical nonlinear model of GaN-based electron devices is presented in the article. The model takes into account low-frequency dispersion due to self-heating and charge-trapping phenomena and provides accurate predictions at frequencies where nonquasi-static effects are important. The model…

SPR biosensing coupled to a digital microfluidic microstreaming system

Elisabeth Galopin, Maxime Beaugeois, Bernard Pinchemel, Jean-Christophe Camart, Mohamed Bouazaoui, V. Thomy

This article reports on a proof-of-concept system composed of a droplet based surface plasmon resonance (SPR) system coupled to a surface acoustic wave (SAW) microfluidic plateform. It is now well established that surface based binding analyses such as SPR are highly influenced by the transport of…
