Free-carrier mobility in GaN in the presence of dislocation walls

J.-L. Farvacque, Z. Bougrioua, I. Moerman

The free-carrier mobility versus carrier density in n-type GaN grown by low-pressure metal-organic vapor- phase epitaxy on a sapphire substrate experiences a particular behavior that consists of the appearance of a sharp transition separating a low- from a high-mobility regime. This separation...

Études pour la réalisation d'un modulateur électro-optique à ondes progressives sur polymères, Studies for the development of a polymer-based traveling-wave electro-optic modulator

Jean-François Larchanché

Le modulateur électro-optique à ondes progressives est un bon candidat pour la modulation à haute fréquence. Une revue des différents types de modulateurs sur niobate de lithium et sur semi-conducteur III-V met en relief les bénéfices de l'utilisation d'une ligne microruban et la..., The traveling-wave electro-optic modulator is a strong candidate for high-frequency modulation. A review of various modulator types based on lithium niobate and III-V semiconductors highlights the benefits of using a microstrip line and the necessity of using a material better suited for this...

Ferroelectric and piezoelectric properties of Nb doped PZT films

T. Haccart, Eric Cattan, Denis Remiens, S. Hiboux, P. Muralt

Pb(Zr,Ti)O3 (PZT) and Pb(Zr,Ti,Nb)O3 (PNZT) thin films were grown on platinized silicon substrates by r.f. magnetron sputtering followed by a post-annealing treatment. The Niobium, Nb, concentration varied from 1 to 7 at.% by increment of 1 at.%. The effects of the Nb introduction on the PZT...

Bonding in skutterudites : combined experimental and theoretical characterization of CoSb3

Isabelle Lefebvre-Devos, M. Lassalle, X. Wallart, Josette Olivier-Fourcade, L. Monconduit, Jean-Claude Jumas

We report on the bonding in skutterudites using the CoSb3 example. The theoretical electronic structure is calculated in both density-functional theory and empirical tight-binding frameworks. It is shown to be in good agreement with x-ray photoemission and photoabsorption experiments, and with Sb...
