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…

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…

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…

Modeling transistor level masking of soft errors in combinational circuits

Ihsen Alouani, Smail Niar, Yassin El Hillali, Atika Rivenq

Technology scaling in modern electronic circuits shrinks the transistor size and dramatically increases the sensitivity of semiconductor devices to radiations. Consequently, soft errors emerged as a serious reliability threat in both sequential and combinational circuits. To accurately estimate…

A co-design space exploration tool for avionic high performance heterogeneous embedded architectures

Geoffroy Pertuisot, Nicolas Belanger, Yassin El Hillali, Smail Niar, Atika Rivenq

Avionics in the helicopter manufacturers' landscape faces new challenges. Whereas customers raise continuously their needs in terms of new functions and embedded systems performances, certification authorities maintain complex rules to fulfill for parallel computing. This constraining…

Contact resistance study of “edge-contacted” metal-graphene interfaces

V. Passi, A. Gahoi, J. Ruhkopf, S. Kataria, Francois Vaurette, E. Pallecchi, H. Happy, M. C. Lemme

The contact resistance RC of "edge-contacted" metal-graphene interfaces is systematically studied. Our experiments demonstrate a reduction of contact resistance by intentional patterning of graphene to create "edge contacts". The parameter space for different hole patterns in…

Characterization and modeling of traps and RF frequency dispersion in AlGaN/AlN/GaN HEMTs

Hector Sanchez-Martin, Oscar Garcia-Perez, Ignacio Íñiguez-De-La-Torre, Susana Perez, Tomás González, Javier Mateos, Philippe Altuntas, N. Defrance, Marie Lesecq, Virginie Hoel, Yvon Cordier, Stephanie Rennesson

The performance of GaN transistors is still limited by physical and fabrication problems, mainly related to different kinds of traps. In this work, virgin transistors reveals strong low frequency dispersion both in the transconductance and output conductance, that we attribute to the presence of…

Personal radio-frequency exposimeters in indoor diffuse environments: Measurement and simulation

Reza Aminzadeh, Arno Thielens, Aliou Bamba, Lamine Kone, Davy Gaillot, M. Lienard, Luc Martens, Wout Joseph

The response of personal exposimeters (PEMs) is studied under diffuse field exposure in indoor environments. A numerical model and a setup for on-body calibration measurements in a reverberation chamber (RC) is proposed for 897–5500 MHz. The proposed numerical simulations are in good agreement with…
