Interferometric technique for scanning near-field microwave microscopy applications

Hind Bakli, Kamel Haddadi, Tuami Lasri

An interferometric technique for scanning near-field microscopy applications is proposed. The method is based on the association of a vector network analyzer, an evanescent microwave coaxial probe and a precise interferometer built up with a power divider, a phase-shifter, and an attenuator.…

Optical properties of gallium nitride heterostructures grown on silicon for waveguiding application

Irma Saraswati, Arnaud Stolz, S. Ko, El Hadj Dogheche, Nji Raden Poespawati, Retno Wigajatri, Didier Decoster

Gallium nitride (GaN) on silicon (Si) is governed by the possibility to use this family of semiconductor for novel optoelectronic devices. GaN layers are deposited by MOCVD on silicon Si (111) using AlGaN buffer layer. We have studied the microstructure quality of the films. From SEM, TEM and AFM…

Phononic crystals patterning by e-beam lithography "dots on the fly" methodology for integration into thermoelectric energy converters

Valeria Lacatena, Maciej Haras, J.F. Robillard, Stéphane Monfray, Thomas Skotnicki, Emmanuel Dubois

A phononic engineered pattern is conceptualized and realized to hinder the phonons propagation and reduce the lattice thermal conductivity. The pattern fabrication methodology is shown and the procedure of integration on suspended membrane for thermal conductivity characterization is depicted. The…

Broadband sound shielding of Lamb waves through a periodic array of junctions

R.P. Moiseyenko, Yan Pennec, R. Marchal, B. Bonello, Bahram Djafari-Rouhani

We study theoretically sub-wavelength physical phenomena such as resonant transmission and broadband sound shielding for Lamb waves propagating in an acoustic metamaterial made of a thin plate drilled with one or two row(s) of rectangular holes. One of the main results is the demonstration of a…

Experimental investigation of the characteristics of the electromagnetic reverberation in the UWB bands

Aliou Bamba, Wout Joseph, Emmeric Tanghe, Luc Martens, Davy Gaillot, M. Lienard, Jose-Maria Molina-Garcia-Pardo, Maria-Teresa Martinez-Ingles

The electromagnetic reverberation time characteristics are investigated at UltraWide Band (UWB) frequencies, i.e., from 2 to 10 GHz. The reverberation time is bandwidth independent and decreases as the frequency increases. Besides, the reverberation ratio - the contribution of the diffuse fields in…

Synthesis and electrical conductivity of multilayer silicene

Patrick Vogt, Pierre Capiod, Maxime Berthe, Andrea Resta, Paola de Padova, Thomas Brühne, Guy Le Lay, B. Grandidier

The epitaxial growth and the electrical resistance of multilayer silicene on the Ag(111) surface has been investigated. We show that the atomic structure of the first silicene layer differs from the next layers and that the adsorption of Si induces the formation of extended silicene terraces…

Modeling and simulation of AlxGayIn1-x-yAs/InP quaternary structure for photovoltaic

Abdelkader Aissat, M. El Bey, Rachid Bestam, Jean-Pierre Vilcot

In this work, we have studied solar cells based on AlGaInAs/InP quaternary structure to describe the behavior of electronics components. To this end, we have developed a simulation program to study the gallium Ga and aluminum Al concentrations effect on respectively the lattice mismatch, the band…

Guided wave in multilayered piezoelectric-piezomagnetic bars with rectangular cross-sections

J.G. Yu, Jean-Etienne Lefebvre, C. Zhang

For the purpose of design and optimization of multilayered piezoelectric-piezomagnetic material (PPC) transducers, wave propagation in these structures has received much attention in past ten years. But the research objects of previous works are only for semi-infinite structures and one-dimensional…
