Excitonic and quasiparticle gaps on Si nanocrystals

Christophe Delerue, Michel Lannoo, Guy Allan

We present calculations of the one- and two-particle excitations in silicon nanocrystals. The one-particle properties are handled in the GW approximation, and the excitonic gap is obtained from the Bethe-Salpeter equation. We develop a tight binding version of these methods to treat clusters up to…

Deformable magnetic mirror for adaptive optics: first results

O. Cugat, P. Mounaix, Skandar Basrour, C. Divoux, G. Reyne

An alternative approach to compact deformable mirrors for adaptive optics is developed. A prototype of a two inch mirror composed of a thin polymer membrane covered with a matrix of permanent magnets and an array of microcoils was built. Several complementary modelling tools were used to study the…

Kinetics of oxydation by scanning probe microscopy : a space-charge-limited model

Emmanuel Dubois, J.L. Bubendorff

This article proposes an enhanced oxidation model for scanning probe microscope (SPM) nanolithography that reproduces the power-of-time law reported for tip-induced anodic oxidation. It is shown that the space charge resulting from nonstoichiometric states strongly limits the oxidation rate. The…

Low field anisotropic magnetostriction of single domain exchange-coupled (TbFe/Fe) multilayers

Henri Le Gall, Jamal Ben Youssef, F. Socha, Nicolas Tiercelin, Vladimir Preobrazhensky, Philippe Pernod

Giant magnetostriction (GMS) reported until now in exchange-coupled multilayers (ECML) present quasi-isotropic magnetostrictive behavior. In the present work it is shown the possibility to induce highly anisotropic GMS at low field with the single domain state in (TbFe/Fe)n multilayers when…
