Unified model of fractal conductance fluctuations for diffusive and ballistic semiconductor devices

Colleen Marlow, Richard Taylor, Theodore P. Martin, B.C. Scannell, H. Linke, M.S. Fairbanks, Gavin D.R. Hall, Ivan Shorubalko, Lars Samuelson, T.M. Fromhold, Carl Brown, Benoit Hackens, Sébastien Faniel, Cédric Gustin, Vincent Bayot, X. Wallart, S. Bollaert, A. Cappy

We present an experimental comparison of magnetoconductance fluctuations measured in the ballistic, quasiballistic, and diffusive scattering regimes of semiconductor devices. In contradiction to expectations, we show that the spectral content of the magnetoconductance fluctuations exhibits an…

Directed assembly for carbon nanotube device fabrication

Jean-Philippe Bourgoin, Jean-Sébastien Borghetti, Pascale Chenevier, Vincent Derycke, Arianna Filoramo, Ludovic Goux, M. F. Goffman, Sébastien Lyonnais, K. Nguyen, G. Robert, S. Streiff, Jean-Marc Bethoux, Henri Happy, Gilles Dambrine, Stéphane Lenfant, Dominique Vuillaume

Chemically and biochemically-directed assembly of nanotubes (NT) for electronics is reviewed. Examples of new field-effect devices prepared this way either for high frequency (40GHz) operation or for applications to an optoelectronics multilevel memory are presented. A route towards (bio)molecular…

Suppression of the pull-in instability for parallel-plate electrostatic actuators operated in dielectric liquids

Bernard Legrand, Anne-Sophie Rollier, Dominique Collard, Lionel Buchaillot

We study electrostatic parallel-plate actuators operated in dielectric liquids. The stable operation zone of the actuators in common liquids is extended far beyond one-third of the initial gap, which is the typical limit of stability for such actuators operated in air. The pull-in effect can even…

Cell Investigation by Terahertz BioMEMS.

A. Treizebre, Bertrand Bocquet, Dominique Legrand, Joël Mazurier

Quite recently, it was found that metal wires can effectively guide terahertz radiation. We report in this communication an original planar excitation of surface wave on a single wire transmission line. This configuration is well suited for the design of THz BioMEMS dedicated to cell investigation…
