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)…

Modeling light-sound interaction in nanoscale cavities and waveguides

Yan Pennec, Vincent Laude, Nikos Papanikolaou, Bahram Djafari-Rouhani, Mourad Oudich, Said El-Jallal, Jean-Charles Beugnot, José Maria Escalante, Alejandro Martinez

The interaction of light and sound waves at the micro and nanoscale has attracted considerable interest in recent years. The main reason is that this interaction is responsible for a wide variety of intriguing physical phenomena, ranging from the laser-induced cooling of a micromechanical resonator…

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…

An SVD-aided efficient bit-loading algorithm for MIMO transmission over spatially correlated channels

Imade Fatani, Marie Zwingelstein, Mohamed Gharbi, François-Xavier Coudoux, Marion Berbineau, Marc G. Gazalet

This paper proposes an efficient bit-loading algorithm for Multiple-Input- Multiple-Output transmission over spatially correlated channels with perfect Channel State Information at both link ends. Based onwater-filling principle, the algorithm does not assume the well-known gap approximation and…

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…

Key parameters of silicon micropillar arrays for solar cell performance optimization

Di Zhou, Yan Pennec, Bahram Djafari-Rouhani, Odile Cristini, Tao Xu, Yannick Lambert, Didier Stiévenard

Surface nanostructuration is an important challenge for the optimization of light trapping design in solar cell. We present simulations of the optical properties and efficiency of nanostructured (micropilars-MPs- or nanocones-NCs-) silicon based solar cells as well as measurements of their optical…
