Transport Inefficiency in Branched-Out Mesoscopic Networks: An Analog of the Braess Paradox

M. G. Pala, S. Baltazar, Peng Liu, Hermann Sellier, B. Hackens, F. Martins, Vincent Bayot, X. Wallart, L. Desplanque, Serge Huant

We present evidence for a counterintuitive behavior of semiconductor mesoscopic networks that is the analog of the Braess paradox encountered in classical networks. A numerical simulation of quantum transport in a two-branch mesoscopic network reveals that adding a third branch can paradoxically...

Joint Carrier Frequency Offset and Channel Estimation for OFDM Systems via the EM Algorithm in the Presence of Very High Mobility

Eric Pierre Simon, Laurent Ros, Hussein Hijazi, Mounir Ghogho

In this paper, the problem of joint carrier frequency offset (CFO) and channel estimation for OFDM systems over the fast time-varying frequency-selective channel is explored within the framework of the expectation-maximization (EM) algorithm and parametric channel model. Assuming that the path...

Electro-elastic moduli and frequency dependence of KN single crystal

R Rouffaud, F. Levassort, M. Pham-Thi, E. Leveugle, Anne-Christine Hladky

— Functional properties of KNbO 3 single crystal are characterized. Large polydomain plates cutted from an as-grown KNbO 3 crystal (oriented along [001] c (45°-cut) direction) are used. At the fundamental resonance (10 MHz), thickness coupling factor is 65% and frequency dependence is measured with...

Role of hydration on the electronic transport through molecular junctions on silicon

N. Clement, David Guérin, S. Pleutin, S. Godey, D. Vuillaume

Molecular electronics is a fascinating area of research with the ability to tune device properties by a chemical tailoring of organic molecules. However, molecular electronics devices often suffer from dispersion and lack of reproducibility of their electrical performances. Here, we show that water...

Cavity-type hypersonic phononic crystals

A. Sato, Yan Pennec, T. Yanagishita, H. Masuda, W. Knoll, Bahram Djafari-Rouhani, G. Fytas

We report on the engineering of the phonon dispersion diagram in monodomain anodic porous alumina (APA) films through the porosity and physical state of the material residing in the nanopores. Lattice symmetry and inclusion materials are theoretically identified to be the main factors which control...
