Electrooptic and converse-piezoelectric properties of epitaxial GaN/Si structures for optoelectronic applications

Mireille Cuniot-Ponsard, Irma Saraswati, S.-M. Ko, Mathieu Halbwax, Y.-H. Cho, N.-R. Poespawati, El Hadj Dogheche

In order to take advantage in all-optic optoelectronic devices, we have investigated the optical and piezoelectric properties of GaN films deposited on (111) silicon. Films are epitaxially grown by MOCVD, thanks to a buffer made of (Al, Ga) N intermediate layers [1]. Structural properties of GaN…

Theoretical and experimental investigation of Lamb waves characteristics in AlN/TiN and AlN/TiN/NCD composite membranes

Ali Soltani, Abdelkrim Talbi, J-C Gerbedoen, Jean-Claude de Jaeger, Philippe Pernod, V. Mortet, A. Bassam

In this study, we present a theoretical and experimental investigations of the zero order quasi-symmetric (S0) Lamb waves mode propagating in AlN/TiN and AlN/TiN/NCD composite membranes. Theoretical analysis of S0 mode characteristics shows that The AlN/TiN membrane enables to achieve smooth…

Influence of an interfacial AlxIn1-xSb layer on the strain relaxation and surface morphology of thin GaSb layers epitaxially grown on GaAs(001)

Mathieu Danoy, Pierre-François Angry, Julien Gavrel, Charlène Brillard, L. Desplanque, Y. Wang, P. Ruterana, Xavier Wallart

This work focuses on the strain relaxation and surface morphology of 10 ML thick GaSb layers on GaAs. It is shown that full relaxation is never reached for this thickness. The use of an AlSb interfacial layer only slightly improves strain relaxation but greatly reduces surface roughness. Finally,…

Carbohydrate-lectin interaction on graphene-coated surface plasmon resonance (SPR) interfaces

Abra Penezic, Geetanjali Deokar, Dominique Vignaud, Emmanuelle Pichonat, Henri Happy, Palaniappan Subramanian, Blaženka Gasparovic, Rabah Boukherroub, Sabine Szunerits

The paper describes the detection of carbohydrate- lectin interaction on graphene-on-metal surface plasmon resonance (SPR) interfaces. Graphene-coated gold-based SPR interfaces were formed through the transfer of large-area graphene grown by chemical vapor deposition (CVD) on polycrystalline Cu…

Negative effective mass density of acoustic metamaterial plate decorated with low frequency resonant pillars

Mourad Oudich, Bahram Djafari-Rouhani, Yan Pennec, M. Badreddine Assouar, Bernard Bonello

We investigate the elastic wave dispersion by a phononic metamaterial plate containing low frequency resonator stubs arranged periodically over the plate. We show that this system not only provides stop bands for wavelengths much larger than the periodicity but also displays negative behavior of…

Cross-talk artefacts in Kelvin probe force microscopy imaging : a comprehensive study

Sophie Barbet, Michka Popoff, Heinrich Diesinger, D. Deresmes, Didier Theron, Thierry Melin

We provide in this article a comprehensive study of the role of ac cross-talk effects in Kelvin Probe Force Microscopy (KPFM), and their consequences onto KPFM imaging. The dependence of KPFM signals upon internal parameters such as the cantilever excitation frequency and the projection angle of…

Dielectric relaxation analysis of Pb(Zr_0.54,Ti_0.46)O₃ thin films: electric field dependence

Freddy Ponchel, N. Sama, Denis Remiens, T. Lasri

350 nm-thick Perovskite PbZr0.54Ti0.46O3 (PZT) thin films were deposited on Al2O3 substrates by sputtering with and without an additional 10-nm-thick TiOx buffer layer. X-ray diffraction patterns showed that in presence of TiOx buffer layer, PZT film was highly oriented along the (111) direction…
