Electro-optic and converse piezoelectric coefficients of epitaxial thin films : GaN grown on Si, and (Sr,Ba)Nb2O6 (SBN) grown on Pt coated MgO (poster)

Mireille Cuniot-Ponsard, Irma Saraswati, Suk-Min Ko, Mathieu Halbwax, Yong-Hoon Cho, El Hadj Dogheche

We report the first measurement of the (r13, r33) Pockels electro-optic coefficients in a SBN thin film and in a GaN thin film grown on silicon. The converse-piezoelectric and electro-absorptive coefficients are simultaneously determined.

Electrical and Chemical studies on Al2O3 passivation activation process

M. Pawlik, J-P. Vilcot, M. Halbwax, D. Aureau, A. Etcheberry, A. Slaoui, T. Schutz-Kuchly, R. Cabal

Al2O3 deposited using Atomic layer Deposition (ALD) technique is known as an excellent material for p-type silicon surface passivation. However a post-deposition annealing step is needed to make the passivation effective. Thanks to coupled electrical measurements (capacitance and photoconductance)…

Temperature dependence of the conduction mechanisms through a Pb(Zr,Ti)O3 thin film

C. Jegou, L. Michalas, T. Maroutian, G. Agnus, M. Koutsoureli, G. Papaioannou, L. Largeau, David Troadec, A. Leuliet, P. Aubert, P. Lecoeur

The conduction mechanisms through a lead zirconate titanate (PZT) thin film grown by pulsed laser deposition with a La0.67Sr0.33MnO3 (LSMO) buffer layer on epitaxial Pt (111) were assessed in the 230-330 K temperature range. X-Ray diffraction and transmission electron microscopy evidenced a…

From 'petal effect' to 'lotus effect' on the highly flexible Silastic S elastomer microstructured using a fluorine based reactive ion etching process

Christophe Frankiewicz, Farzam Zoueshtiagh, Abdelkrim Talbi, Jeremy Streque, Philippe Pernod, Alain Merlen

A fluorine-based reactive ion etching (RIE) process has been applied on a new family of silicone elastomers named 'Silastic S' for the first time. Excellent mechanical properties are the principal advantage of this elastomer. The main objective of this study was (i) to develop a new…

Influence of processing gases on the properties of cold atmospheric plasma SiOxCy coatings

H. Hamze, Maude Jimenez, D. Deresmes, Arnaud Beaurain, Nicolas Nuns, Michel Traisnel

Thin layers of SiOxCy (y = 4−x and 3 ≤ x ≤ 4) were applied using a cold atmospheric plasma torch on glass substrates. The aim was to investigate using Atomic Force Microscopy (AFM), X-ray photoelectron spectroscopy (XPS) and time-of-flight secondary ion mass spectrometry (Tof-Sims) the influence of…

Longitudinal and transversal polarization switching in strained ferroelectrics

Laurent Baudry, Igor A. Luk'Yanchuk, A. Razumnaya

Using the multicomponent Landau-Devonshire functional we study the field-induced polarization switching in c-oriented ferroelectric phase of epitaxial perovskite film and found that two different regimes are possible: (i) longitudinal switching with change of the polarization modulus and (ii)…

Electrical characterization of semiconductor nanowires by scanning tunneling microscopy

Corentin Durand, Pierre Capiod, Maxime Berthe, Tao Xu, Jean-Philippe Nys, Renaud Leturcq, Philippe Caroff, B. Grandidier

In order to understand the structural and electronic properties of semiconductor nanowires, scanning tunneling microscopy is an appealing technique that can supplement transmission electron microscopies and conventional electrical characterization techniques. It is able to probe the surface of…

Multiuser phase coded costas signals with improved cross-correlation and partial cross-ambiguity properties

Nadjah Touati, Charles Tatkeu, Atika Rivenq, Thierry Chonavel

Costas codes are a variant of frequency hopping codes that achieve the «thumbtack» auto-ambiguity function needed in radar applications. However, they may show poor cross- ambiguity properties when selected and assigned randomly which makes them poorly adapted to multiuser radar applications. In…
