Ion-beam effect on functional properties of La2Ti2O7 piezoelectric thin films and nanoislands

A. Ferri, S. Saitzek, Z. Shao, A. Bayart, G. Declercq, Jean Costecalde, Denis Remiens, D. Deresmes, David Troadec, Rachel Desfeux

Low-dimensional material can display unique physical phenomena allowing an interesting way for the development of new technologies. In addition, owing the environmental requirements about electronic devices (ferroelectric memories, M/NEMS...), new lead-free piezoelectrics need to be created. In…

Electrical and chemical studies on Al2O3 passivation activation process

Matthieu Pawlik, Jean-Pierre Vilcot, Mathieu Halbwax, D. Aureau, A. Etcheberry, A. Slaoui, T. Schutz-Kuchly, R. Cabal

Passivation process is a key feature to improve the efficiency of silicon solar cells. So far, a 20nm-thick layer of Al2O3 grown by Plasma Enhanced Atomic Layer Deposition (PE-ALD) followed by a 450°C anneal during 15 to 30 min gives the best results in surface carrier recombination velocities on p…

Synthesis and characterization of BNT thin films

Sara Abou Dargham, Jihane Jabbour, Youssef Zaatar, Jamal Assaad, Antonio Khoury, Denis Remiens, Doumit Zaouk

Polycrystalline piezoelectric lead-free Bi0.5Na0.5TiO3 (abbreviated as BNT) thin films were deposited on glass substrates by an optimized Sol-Gel process using the Electrospray technique. X-ray Diffraction (XRD) analysis showed that after heating the films at 650˚C for 1 hour, dense and well…

Nonlinear measurement of non periodic pulse train with mixer based NVNA dedicated to radar power amplifier

Vincent Bridier, Damien Ducatteau, Maxime Olivier, Hans-Joachim Simon, François Graux, Philippe Eudeline, Gilles Dambrine

A measurement of time domain waveforms using a commercial two ports mixer based NVNA to measure a non periodic repetitive radar pulse train as a periodic one was performed. Then for the first time a 20GHz six port mixer based NVNA able to measure three different frequencies at the same time is…

Fabrication and characterization of 2D phononic crystals based on lithium niobate substrate and nickel pillars

Yu Du, Abdelkrim Talbi, Jean-Claude Gerbedoen, Sergey Yankin, Philippe Pernod, Vladimir Preobrazhensky, Olivier Bou Matar

This work presents experimental investigation of interaction between surface acoustic waves and 2D surface Phononic crystals (PnCs). The PnC is made of 2D array of resonant nickel pillars arranged in different symmetric lattices, and deposited on lithium niobate (Y128 cut) substrate. Measurement of…
