Temperature dependence of the conduction mechanisms through a Pb(Zr,Ti)O3 thin film

C. Jegou, L. Michalas, T. Maroutian, G. Agnus, M. Koutsoureli, G. Papaioannou, L. Largeau, David Troadec, A. Leuliet, P. Aubert, P. Lecoeur

The conduction mechanisms through a lead zirconate titanate (PZT) thin film grown by pulsed laser deposition with a La0.67Sr0.33MnO3 (LSMO) buffer layer on epitaxial Pt (111) were assessed in the 230-330 K temperature range. X-Ray diffraction and transmission electron microscopy evidenced a…

Experimentation and modeling of node energy consumption in wireless sensor networks

Román Igual-Pérez, Alexandre Boé, Nathalie Rolland, Laurent Clavier

Wireless sensor networks could be widely used in a large variety of applications such as smart cities, structural health monitoring. However, their large scale deployment is limited by the lifetime of the nodes. A joint optimization of both hardware and software is a promising solution to decrease…

Key parameters of CVD-grown graphene on copper foil and its transfer for radio-frequency applications

Wei Wei, Geetanjali Deokar, Mohamed Moez Belhaj, D. Mele, Emiliano Pallecchi, Emmanuelle Pichonat, Dominique Vignaud, Henri Happy

To synthesize monolayer graphene and realize defect free transfer for electronic devices application are still challenges. In this letter, we present the fabrication and characterization of graphene field effect transistor (GFET), with respect to key parameters of graphene growth on Cu by chemical…

Caractérisation quantitative des capacités sous échelle de 10 nm avec un interférométrique scanning-microwave-microscopy

Fei Wang, Nicolas Clément, Damien Ducatteau, David Troadec, Bernard Legrand, Gilles Dambrine, Didier Theron

Nous présentons une façon de caractériser quantitativement des capacités sous échelle de 10 nm à l'aide d'un scanning-microwave-microscope modifié avec un interféromètre (iSMM). Des milliers de capacités à l'échelle nanométrique (nanoplots) et un kit de capacités de calibrages sont…

Near-self-imaging cavity for three-mode optoacoustic parametric amplifiers using silicon microresonators

J. Liu, F. A. Torres, Y. Ma, C. Zhao, L. Ju, D. G. Blair, S. Chao, I. Roch-Jeune, R. Flaminio, C. Michel, K.Y. Liu

Three-mode optoacoustic parametric amplifiers (OAPAs), in which a pair of photon modes are strongly coupled to an acoustic mode, provide a general platform for investigating self-cooling, parametric instability and very sensitive transducers. Their realization requires an optical cavity with…

[Review] Generation of transversal envelope soliton in polymeric and wooden rods

M. de Billy, Anne-Christine Hladky

This paper is concerned with the probing of the transversal envelope solitons propagation in circular waveguides when a set of requirements (non-linearity and dispersion) are fulfilled in the waveguide and balanced. The basic idea is to analyze the shape of an acoustic pulse after it has traveled…

Millimeter-wave in situ tuner : an efficient solution to extract the noise parameters of SiGe HBTs in the whole 130-170 GHz range

Marina Deng, Laurent Poulain, Daniel Gloria, Thomas Quémerais, Pascal Chevalier, Sylvie Lepilliet, Francois Danneville, Gilles Dambrine

SiGe HBT noise parameters ( , and ) are for the first time extracted in the entire 130 - 170 GHz frequency range. This achievement is realized using a D-band on-chip source-pull system, which includes an impedance tuner integrated with the transistor under test. On-wafer noise power measurements on…

A MIMO random channel generator for indoor power-line communication

Kassim Khalil, Marc G. Gazalet, Patrick Corlay, François-Xavier Coudoux, M Gharbi

Multiple-input multiple-output (MIMO) technology has already been used in power-line communication (PLC). An accurate description of MIMO channels for PLC network topologies is of great interest and importance in the development and testing of digital communication algorithms. However, the…

Effect of thickness and deposition rate on the structural and magnetic properties of evaporated Fe/Al thin films

M. Mebarki, A. Layadi, L. Kerkache, A. Benabbas, Nicolas Tiercelin, Vladimir Preobrazhensky, Philippe Pernod

We report experimental results on the structural and magnetic properties of Fe thin films deposited by thermal evaporation onto polycrystalline Al substrates. The effect of thickness t (in the 76 to 431 nm range) and deposition rate are investigated. The texture, the strain, and the grain size…
