Theory of self-assembled nanoparticle networks as logic building blocks

Fabrizio Cleri, Sergio Carrillo, Christophe Krzeminski

Recently, self-assembled networks of functionalized nano particles (NPSAN) were proposed as a prototype of innovative devices [1], with switchable NP-NP links. Thanks to the chemical properties of the surface molecules, these would ultimately show memristive behaviour, as building blocks of a…

Architectures supramoléculaires sur la surface de Si(111)-B

Younes Makoudi, Judicaël Jeannoutot, Matthieu Beyer, Bulent Baris, B. Grandidier, Frank Palmino, Frédéric Cherioux

La formation des réseaux supramoléculaires périodiques à grande échelle sur une surface est d'un intérêt primordial pour le développement de composants intelligents [1]. Cet objectif nécessite la synthèse des molécules organiques ayant des fonctions appropriées en vue d'obtenir des…

Enhanced efficiency by the effect of strain on the structure of a solar cell

Abdelkader Aissat, Rachid Bestam, M. El Bey, Jean-Pierre Vilcot

This paper is expected at the study of Ga1-xInxP/GaAs based solar cell. The effects of indium concentration, lattice parameter mismatch and thickness of the SiO2 insulating layer on the characteristics and efficiency of the Ga1-xInxP/GaAs structure were investigated. We noticed that for higher…

Improved wet chemical transfer process to obtain clean high quality graphene

Geetanjali Deokar, Jean-Louis Codron, Emmanuelle Pichonat, Xavier Wallart, Henri Happy, Dominique Vignaud

Graphene growth on metal substrates (Cu, Ni etc.) by catalyzed chemical vapor deposition (CVD) is a highly suitable method for large scale production [1,2]. However, graphene based electronic devices full realization requires a clean and reproducible graphene transfer on non-conducting substrates,…

Optical and microstructural properties into nanoporous GaN films grown on sapphire by metal organic chemical vapor deposition

Bandar Alshehri, S.-M. Lee, J.-H. Kang, Karim Dogheche, S.-H. Gong, S.-W. Ryu, E. Dumont, Y.-H. Cho, El Hadj Dogheche

Gallium Nitride (GaN) thin films have been prepared on sapphire by metal organic chemical vapor deposition (MOCVD) technique and a chemical etching method using KOH is used to develop nanoporous structures [1]. We present comparative investigations of porous and nonporous GaN layers. While the…

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.

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…
