Modeling and optimization of core/shell p-i-n Si/Si0.2Ge0.8 nanowire for photovoltaic

Fethi Benyettou, Abdelkader Aissat, Isabelle Berbezier, Jean-Pierre Vilcot

In this work we propose a modeling and simulation of core/shell p-i-n Si/Si0.2Ge0.8 nanowire for photovoltaic. In the first step of this work, we have compared the core/shell p-i-n homo-junction Si and heterojunction Si/Si0.2Ge0.8 Nanowire (NW) solar cell having a length of 3 mu m and a radius of 0…

Pillar-type acoustic metasurface

Yabin Jin, Bernard Bonello, Rayisa P. Moiseyenko, Yan Pennec, Olga Boyko, Bahram Djafari-Rouhani

We theoretically investigate acoustic metasurfaces consisting of either a single pillar or a line of identical pillars on a thin plate, and we report on the dependence on the geometrical parameters of both the monopolar compressional and dipolar bending modes. We show that for specific dimensions…

Quantitative determination of small dielectric and loss tangent contrasts in liquids

Hind Bakli, Kamel Haddadi

Accurate measurement of dielectric constant and loss tangent in liquid media in the frequency range 2-6 GHz is proposed in this paper. The measurement set-up is based on an open-ended coaxial probe instrumented with a home-made microwave interferometer. The interferometer is used to match the…

Non destructive evaluation of bi-material structures: a case study

Lynda Chehami, Nico F. Declercq, Paul Lohmuller, Pascal Pomarede, Boris Pitrowski, Fodil Meraghni, Esam Ahmed Mohamed, Othmane Ez-Zahraouy

Due to their specific elastic properties (high stiffness to mass ratio), regular microstructure materials (architectural materials), are widely used in industry. This work deals with nondestructive evaluation of a 3D bi-material structure made of an architectural ABS polymer embedded in an Epoxy…

A text-dependent speaker-recognition system

Dany Ishac, Antoine Abche, Elie Karam, Georges Nassar, Dorothée Debavelaere-Callens

In this work, a voice recognition approach is developed and presented. It is a based on acquiring the signal of vocal cords' vibrations of a person using a piezoelectric transducer element attached on a collar wrapped around the neck. The recognition is then based on the vocal cords vibrations…

The influence of the presence of a defect in a structure on the cross-correlation, application to the tubular structure

Karl Hourany, Youssef Zaatar, Farouk Benmeddour, Emmanuel Moulin, Dorothée Debavelaere-Callens, Jamal Assaad

The aim of this paper is to verify experimentally the constant possibility of performing a Structural Health Monitoring (SHM) in a medium by studying the ambient noise present therein. First, we will illustrate the equivalence between the Green's function and the cross-correlation, then we…

Complexity of the hot carrier relaxation in Si nanowires compared to bulk

Jing Li, Yann-Michel Niquet, Christophe Delerue

We investigate the relaxation of hot carriers by emission of phonons in bulk Si and Si nanowires (NWs) with an identical atomistic methodology. The phonon scattering is strongly enhanced in NWs. At high excitation energy, the carrier cooling is faster in NWs than in bulk, mainly due to the coupling…
