Epitaxial Bi2Sr2Co2Oy thin films as a promising p-type transparent conducting oxides

Shufang Wang, Liqing Sun, Hongrui Zhang, El Hadj Dogheche, Jianglong Wang, Guangsheng Fu

Transparent conductive p-type Bi2Sr2Co2Oy thin films were epitaxial grown on LaAlO3 substrate by pulsed laser deposition. Film with thickness of 50 nm showed a room temperature resistivity of about 5.5 mΩ cm and an average optical transmittance of about 51% in the visible region, resulting in a...

A modal formulation for the propagation of guided waves in straight and curved pipes and the scattering at their junction

M. El Bakkali, A. Lhémery, V. Baronian, Sébastien Grondel

The well-established semi-analytic finite element (SAFE) method for predicting guided wave propagation in straight guides is extended to deal with curved pipes using curvilinear coordinates system, following developments by Treyssède and Laguerre [J. Sound Vib. 329 1702-16 (2010)] for helical wires...

Finite element analysis and experimental study of surface acoustic wave propagation through two-dimensional pillar-based surface phononic crystal

S. Yankin, Abdelkrim Talbi, Y. Du, Jean-Claude Gerbedoen, Vladimir Preobrazhensky, Philippe Pernod, Olivier Bou Matar

We study both theoretically and experimentally the interaction of surface elastic waves with 2D surface phononic crystal (PnC) on a piezoelectric substrate. A rigorous analysis based on 3D finite element method is conducted to calculate the band structure of the PnC and to analyze the transmission...

A focusing technique based on a data spatial diversity at millimetre-wave frequency

Michael Bocquet, Atika Rivenq, Christophe Loyez, Nathalie Rolland

This paper presents a new topology of data coding and data broadcasting exclusively sent to a specific location area. The proposed technique exploits specifically different received signals to focus energy and to rebuild information intelligibly only for a chosen position. By this way, the receiver...

Optical waveguiding properties into porous gallium nitride structures investigated by prism coupling technique

Bandar Alshehri, Seung-Min Lee, Jin-Ho Kang, Su-Hyun Gong, Sang-Wan Ryu, Yong-Hoon Cho, El Hadj Dogheche

In order to modulate the refractive index and the birefringence of Gallium Nitride (GaN), we have developed a chemical etching method to perform porous structures. The aim of this research is to demonstrate that optical properties of GaN can be tuned by controlling the pores density. GaN films are...

Effect of interface configurations on the dynamic scaling behavior of Pb(Zr0.53Ti0.47)O3 thin films

Kui Li, Nossikpendou Sama, Tao Li, Denis Remiens, Gang Du, Xianlin Dong, Genshui Wang

The ferroelectric hysteresis and the scaling relations of hysteresis area ⟨A⟩ against field amplitude E and frequency f in Pb(Zr0.53Ti0.47)O3 thin films using platinum and LaNiO3 (LNO) as both bottom and top electrodes were systematically investigated. Interestingly, it was found that the influence...

A synthesis of theoretical and experimental study on power line communication over an aircraft tree-shaped network

Virginie Degardin, Pierre Laly, M. Lienard, Pierre Degauque

This paper gives an overview of the theoretical and experimental approach which has been carried out in order to study the feasibility of broadband power line communication in aircraft. The network which has been chosen corresponds to part of a cabin lighting system and whose tree shape...
