Temperature dependence of dynamic hysteresis behavior in Pb0.4Sr0.6TiO3 ferroelectric films

Kui Li, Tao Li, Gang Du, Denis Remiens, Xianlin Dong, Genshui Wang

The temperature (T) dependence of dynamic hysteresis behavior is investigated in low temperature crystallized Pb0.4Sr0.6TiO3 thin films between 85 K and 340 K. It was found that the temperature scaling relations for hysteresis area 〈A〉, remnant polarization Pr and coercive field Ec take the…

Cross-talk artefacts in Kelvin probe force microscopy imaging : a comprehensive study

Sophie Barbet, Michka Popoff, Heinrich Diesinger, D. Deresmes, Didier Theron, Thierry Melin

We provide in this article a comprehensive study of the role of ac cross-talk effects in Kelvin Probe Force Microscopy (KPFM), and their consequences onto KPFM imaging. The dependence of KPFM signals upon internal parameters such as the cantilever excitation frequency and the projection angle of…

Bragg band gaps tunability in an homogeneous piezoelectric rod with periodic electrical boundary conditions

Sébastien Degraeve, Christian Granger, Bertrand Dubus, Jerome O. Vasseur, Mai Pham Thi, Anne-Christine Hladky

An homogeneous piezoelectric rod is shown to exhibit Bragg band gaps when an electrical boundary condition is applied periodically with the help of metallic electrodes. An analytical model is developed which formulation depends on the applied electric boundary condition and reveals that Bragg band…

Negative effective mass density of acoustic metamaterial plate decorated with low frequency resonant pillars

Mourad Oudich, Bahram Djafari-Rouhani, Yan Pennec, M. Badreddine Assouar, Bernard Bonello

We investigate the elastic wave dispersion by a phononic metamaterial plate containing low frequency resonator stubs arranged periodically over the plate. We show that this system not only provides stop bands for wavelengths much larger than the periodicity but also displays negative behavior of…

Hypersonic band gap in an AlN-TiN bilayer phononic crystal slab

S. Hemon, Abdellatif Akjouj, A. Soltani, Yan Pennec, Y. El Hassouani, Abdelkrim Talbi, V. Mortet, Bahram Djafari-Rouhani

We show both theoretically and experimentally the existence of a complete band gap in a phononic crystal (PnC) constituted by periodical air holes drilled in a solid bi-layer slab. The composite slab is formed with an aluminum nitride (AlN) layer deposited on a titanium nitride (TiN) thin metallic…

Distributional upper bound on the interference in spatial wireless multiuser ultrawideband communication systems

Gareth W. Peters, Ido Nevat, Laurent Clavier, François Septier

We develop a novel distributional upper bound on the interference created in an ultra-wideband wireless communication systems under two general assumptions: the first is that there is an unknown number of interferers who are distributed according to a homogeneous Poisson point process randomly in…

Joint estimation of state and noise parameters in a linear dynamic system with impulsive measurement noise: Application to OFDM systems

Nouha Jaoua, Emmanuel Duflos, Philippe Vanheeghe, Laurent Clavier, François Septier

Interference mitigation is one of the main challenges in wireless communication, especially in ad hoc networks. In such context, the Multiple Access Interference (MAI) is known to be of an impulsive nature. Therefore, the conventional Gaussian assumption is inadequate to model this type of…

On detection method for soft iterative decoding in the presence of impulsive interference

Vincent Dimanche, Alban Goupil, Laurent Clavier, Guillaume Gelle

This paper deals with the performance improvement of soft iterative decoders in impulsive interference modeled by additive noise. In case of $alpha$-stable noise, the inputs of the belief propagation decoder are too complex to compute. We propose to use an approximation of the log likelihood ratio…

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…
