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…

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…

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…

Theoretical investigation of the phonon-limited carrier mobility in (001) Si films

Jing Li, Evelyne Lampin, Christophe Delerue, Yann-Michel Niquet

We calculate the phonon-limited carrier mobility in (001) Si films with a fully atomistic framework based on a tight-binding (TB) model for the electronic structure, a valence-force-field model for the phonons, and the Boltzmann transport equation. This framework reproduces the electron and phonon…

Growth of c -Axis-Oriented BiCuSeO Thin Films Directly on Si Wafers

Xiaolin Wu, Linjie Gao, Pascal Roussel, El Hadj Dogheche, Jianglong Wang, Guangsheng Fu, Shufang Wang

Single-phase, c-axis-oriented BiCuSeO thin films have been directly grown on the commercial silicon (001) wafers without any surface pretreatment by using pulsed laser deposition. X-ray diffraction pole figure confirms that the film does not have any ab-plane texture, whereas cross-sectional…

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…

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…

Nickel Decorated on Phosphorous-Doped Carbon Nitride as an Efficient Photocatalyst for Reduction of Nitrobenzenes

Anurag Kumar, Pawan Kumar, Chetan Joshi, Manvi Manchanda, Rabah Boukherroub, Suman L Jain

Nickel nanoparticle-decorated phosphorous-doped graphitic carbon nitride (Ni@g-PC 3 N 4) was synthesized and used as an efficient photoactive catalyst for the reduction of various nitrobenzenes under visible light irradiation. Hydrazine monohydrate was used as the source of protons and electrons…

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…
