Effect of alkyl substituents on the adsorption of thienylenevinylene oligomers on the Si (100) surface

B. Grandidier, Jean-Philippe Nys, Didier Stiévenard, Christophe Krzeminski, Christophe Delerue, Pierre Frere, Phillippe Blanchard, Jean Roncali

The adsorption of thienylenevinylene oligomers on the Si(100) surface has been investigated using scanning tunneling microscopy. The mode of substitution of the thiophene ring exerts a strong influence on the adsorption configurations and the images of the oligomer based on 3,4-dihexyl thiophene…

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…

PbZr0.52Ti0.48O3 and SrBi2Nb2O9 ferroelectric oxides integrated with YBa2Cu3O7 superconductor in multilayers epitaxially grown by pulsed laser deposition

Jean-René Duclere, Maryline Guilloux-Viry, A. Perrin, Caroline Soyer, Eric Cattan, Denis Remiens, A. Dauscher, Sébastien J. Weber, B. Lenoir

Multilayers of PbZr0.52Ti0.48O3 (PZT) or SrBi2Nb2O9 (SBN) ferroelectrics (F) and YBa2Cu3O7 (YBaCuO) superconductor (S) have been grown by pulsed laser deposition. F/S or S/F bilayers as well as S/F/S trilayers deposited on SrTiO3 and MgO were epitaxially grown, as evidenced by x-ray diffraction (…
