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...

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...

Crosstalk measurement of DOS-like switch using InP narrow deep-etched waveguides

Marie Lesecq, Maxime Beaugeois, Sophie Maricot, Jean-Pierre Vilcot

We report on the performance of an optical switch based on the use of narrow deep-etched InP waveguides. A DOS-like structure has been designed and fabricated. First characterization results are reported. They show an optical crosstalk value close to -20dB.

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...

Tight-binding description of the quasiparticle dispersion of graphite and few-layer graphene

A. Grüneis, Claudio Attaccalite, L. Wirtz, H. Shiozawa, R. Saito, T. Pichler, A. Rubio

A universal set of third–nearest neighbour tight–binding (TB) parameters is presented for calculation of the quasiparticle (QP) dispersion of N stacked sp2 graphene layers (N = 1 . . . ∞) with AB stacking sequence. The QP bands are strongly renormalized by electron–electron interactions which...
