Development of a patch antenna based on a Polyaniline/Carbon coated Cobalt composite

Z. Hamouda, J.-L. Wojkiewicz, A.A. Pud, Lamine Kone, C. Hamouda, S. Bergheul, T. Lasri

In this study, a patch antenna including a thick film made of a composite material based on Polyaniline (PANI) and Carbon coated Cobalt (CCo) is investigated. Conception, simulation, realization and characterization steps are presented. The morphology of the obtained composite was studied via…

Enhanced ultraviolet luminescence of ZnO nanorods treated by high-pressure water vapor annealing (HWA)

Amer Al-Nafiey, Brigitte Sieber, B. Gelloz, Ahmed Addad, M. Moreau, Julien Barjon, Maria Girleanu, Ovidiu Ersen, Rabah Boukherroub

Zinc oxide nanorods (ZnO NRs), synthesized by a low temperature chemical method, were postannealed at 260°C in air and under high pressure water vapor (HWA) at 1.3-3.9 MPa. We found that the UV luminescence intensity increased by a factor of 2-3 after HWA annealing compared to that observed after…

Investigations on the mechanical properties of the elementary thin films composing a CuIn1−xGaxSe2 solar cell using the nano indentation technique.

Hocine Abib, Alain Iost, Alex Montagne, Khadidja Rahmoun, Boubakeur Ayachi, Jean-Pierre Vilcot

The aim of this work is to assess the mechanical properties of the different layers composing a CIGS based solar cell. Fabrication uses the magnetron sputtering deposition technique (except for the CdS layer which was deposited using chemical bath deposition process). We performed several…

Electronic structure investigation of Al0.7Ga0.3As/GaAs nanometric heterostructures by Kelvin force microscopy

Sylvain Pouch, Francois Triozon, Nicolas Chevalier, Thierry Melin, Yann Michel Niquet, Lukasz Borowik

Kelvin force microscopy provides a spatially resolved measurement of the surface potential, which is related to the energetic band structure of a material. The goal of this work is to investigate the surface potential on Al0.7Ga0.3As and GaAs heterostructures with a decreasing layer thickness up to…

Bulk acoustic wave transformer employing periodically polled array of piezoelectric rods

Victor Plessky, Ventsislav Yantchev, C. Granger, Anne-Christine Hladky

Multilayer bulk acoustic wave transformer employing a periodical array of piezoelectric rods with alternating polarization is experimentally demonstrated for the first time. Voltage transformation coefficient in excess of 6 was measured at a frequency of 150kHz, providing thus a solid experimental…

Improved performance of flexible CMOS technology using ultimate thinning and transfer bonding

Emmanuel Dubois, Justine Philippe, Matthieu Berthomé, J.F. Robillard, Christophe Gaquière, Francois Danneville, Daniel Gloria, Christine Raynaud

Based on a simple process referred to as ultimate thinning-and-transfer-bonding (UTTB), this paper shows that the high-frequency performance of advanced CMOS technologies can be combined with mechanical flexibility and transparency. The invariance upon thinning, transfer and flexure of both DC and…

Broadband dielectric characterization of aqueous saline solutions by an interferometer-based microwave microscope

S. Gu, Tianjun Lin, T. Lasri

The complex dielectric permittivity of aqueous saline solutions has been determined in the frequency range [2-18 GHz] with a home-made near-field microwave microscope. The instrument is built on a vector network analyzer, a matching network, and an evanescent microwave probe. The interferometer-…

Inverse saffman-taylor experiments with particles lead to capillarity driven fingering instabilities

Ilyesse Bihi, Michael Baudoin, Jason E. Butler, Christine Faille, Farzam Zoueshtiagh

Using air to displace a viscous fluid contained in a Hele-Shaw cell can create a fingering pattern at the interface between the fluids if the capillary number exceeds a critical value. This Saffman-Taylor instability is revisited for the inverse case of a viscous fluid displacing air when partially…
