Scanning Gate Spectroscopy of transport across a Quantum Hall Nano-Island

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

We explore transport across an ultra-small Quantum Hall Island (QHI) formed by closed quan- tum Hall edge states and connected to propagating edge channels through tunnel barriers. Scanning gate microscopy and scanning gate spectroscopy are used to first localize and then study a single QHI near a...

Ultrafast optical technique for measuring the electrical dependence of the elasticity of piezoelectric thin film : demonstration on AlN

Arnaud Devos, P. Emery, E. Defay, N. Ben Hassine, G. Parat

We present a technique based on ultrafast acoustics which permits us to measure the electrical dependence of the elastic properties of a thin piezoelectric layer. Ultrafast acoustics offers a unique way of measuring elastic properties of thin-layer in a non-destructive way using ultrashort optical...

Laser ultrasonics and mode conversion for flaw depth gauging

Frédéric Faëse, Frédéric Jenot, Mohammadi Ouaftouh, Marc Duquennoy, Mohamed Ourak

Compared to earliest non destructive testing and evaluation methods based on transducers, laser ultrasonics shows specific advantages. It is a non-contact method combining a high spatial resolution and a large bandwidth, allowing high temperature and/or geometrically complex materials testing. In...

Fundamentals of charged devices : energy changes in a capacitor medium

J.S. Young, Laurent Baudry

Capacitors and derivative devices continue to be as relevant as ever, both at the frontiers of scientific and technological research and in the development of commercial products. Central to such pursuits is the essential requirement that all aspects of the work done in charging or discharging...

An accurate performance analysis of an FFR scheme in the downlink of cellular systems under large-shadowing effect

Benoît Pijcke, Marc G. Gazalet, Marie Zwingelstein, François-Xavier Coudoux

We address the problem of analyzing the performances of interference-limited cellular networks in large-scale shadowing environments. Focusing on the fractional frequency reuse (FFR) framework, we examine how to optimally assign mobile users in a cell either to the full frequency reuse part or to...
