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…

Planning the electron traffic in semiconductor networks: A mesoscopic analog of the Braess paradox encountered in road networks

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

By combining quantum simulations of electron transport and scanning-gate microscopy, we have shown that the current transmitted through a semiconductor two-path rectangular network in the ballistic and coherent regimes of transport can be paradoxically degraded by adding a third path to the network…

Si-nanorod-based plasmonic metamaterials : modeling and experiment

Silvia Peruch, Jean-Sébastien Bouillard, Daniel O'Connor, Wayne Dickson, Gregory Wurtz, Anatoli Zayats, Xiang-Lei Han, Tahsin Akalin, Guilhem Larrieu

Plasmonic metamaterials based on assemblies of metallic nanoparticles (MNPs) have finely tunable optical properties, which can be tailored for different applications, from sensing to waveguiding [1], [2]. Nanorods and nanorod arrays have been widely studied both theoretically and experimentally. In…

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…
