Experimental demonstration of anomalous nonreciprocal optical response of 1D periodic magnetoplasmonic nanostructures

L. Halagacka, Mathias Vanwolleghem, Francois Vaurette, Jamal Ben Youssef, Philippe Gogol, N. Yam, K. Postava, B. Dagens, J. Pistora

In this paper we analyze the optical and transversal magnetooptical (MO) response of magnetoplasmonic (MP) nanostructures. The MP structure is a 1D periodic gold grating fabricated by lift-off technique on the MO dielectric substrate (Bi-substituted yttrium iron garnet BixY3−xFe5O12). Following our…

Surface acoustic wave bandgaps for conical pillars on a piezoelectric substrate

Abdelali Mrabti, Mourad Oudich, Abdellatif Akjouj, Yan Pennec, Bahram Djafari-Rouhani, Abdelkrim Talbi, Jérémy Streque, Yu Du, Ali Soltani, Philippe Pernod

We report theoretically on the band structure of a square lattice phononic crystal made up of nickel (Ni) conical pillars deposited on the surface of a semi-infinite LiNbO3 substrate. Calculations have been performed with a 3D finite element method taking into account material anisotropy and…

Back-gated microwave field-effect transistors based on transferred CVD-grown graphene

Wei Wei, Mohamed Moez Belhaj, Geetanjali Deokar, D. Mele, Emiliano Pallecchi, Emmanuelle Pichonat, Dominique Vignaud, Henri Happy

Graphene based transistors have drawn growing interest from both industries and Laboratories [1-3]. In this work, we present both fabrication process and characterization of graphene field-effect transistors. Large scale monolayer graphene was grown by chemical vapor deposition (CVD) on Cu foils…

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…

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…

High polarization high breakdown voltage AlN/GaN-on-silicon transistors

Nicolas Herbecq, Isabelle Roch-Jeune, F Medjdoub

We have developed a back-side process on AlN/GaN-on-Si DHFETs in order to drastically enhance their electrical performances. With a buffer thickness of 1.8 μm, the Si substrate has been locally etched up to the buffer layers between the drain and the gate. After local silicon removal, the three-…

Characterisation of early HepG2/3a cell response to a microfluidic culture in liver biochips using multi-parametric real time image processing

Marie Naudot, Patrick Paullier, Thomas Dargent, Vincent Senez, Zaher Kharboutly, Isabelle Claude, Eric Leclerc

We developed an image processing protocol to perform time lapse fluorescent analysis in microfluidic biochips. Using three probes to follow three parameters: the number of cell nucleus, the mitochondrial activity and the cell death, we have investigated the behaviour of HepG2/C3a under microfluidic…
