Inline high frequency ultrasonic particle sizer

Fabrice Lefebvre, J. Petit, Georges Nassar, P. Debreyne, Guillaume Delaplace, Bertrand Nongaillard

This paper reports the development of a new method of particle sizing in a liquid. This method uses high frequency focused ultrasounds to detect particles crossing the focal zone of an ultrasonic sensor and to determine their size distribution by processing the reflected echoes. The major advantage…

Electronic structure and transport properties of Si nanotubes

J. Li, T. Gu, C. Delerue, Y.M. Niquet

The electronic structure and the transport properties of Si nanotubes with outer diameter between 2 and 20 nm are investigated using fully atomistic simulations. A formula is given for the energy of the band edges versus diameter and thickness. The phonon-limited mobility of electrons and holes is…

Wafer-scale integration of piezoelectric actuation capabilities in nanoelectromechanical systems resonators

Denis Dezest, Fabrice Mathieu, Laurent Mazenq, Caroline Soyer, Jean Costecalde, Denis Remiens, Olivier Thomas, Jean-François Deü, Liviu Nicu

In this work, we demonstrate the integration of piezoelectric actuation means on arrays of nanocantilevers at the wafer scale. We use lead titanate zirconate (PZT) as piezoelectric material mainly because of its excellent actuation properties even when geometrically constrained at extreme scale

Modelling of silicon oxynitridation by nitrous oxide using the reaction rate approach

Christophe Krzeminski

Large technological progress in oxynitridation processing leads to the introduction of silicon oxynitride as ultra-thin gate oxide. On the theoretical side, few studies have been dedicated to the process modelling of oxynitridation. Such an objective is a considerable challenge regarding the…

Coherent tunnelling across a quantum point contact in the quantum Hall regime

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

The unique properties of quantum Hall devices arise from the ideal one-dimensional edge states that form in a two-dimensional electron system at high magnetic field. Tunnelling between edge states across a quantum point contact (QPC) has already revealed rich physics, like fractionally charged…

Surface states and conductivity of silicon nano-wires

U.K. Bhaskar, T. Pardoen, V. Passi, J.P. Raskin

The transport characteristics of low dimensional semiconductors like silicon nano-wires (SiNWs) rarely conform to expectations from geometry and dopant density, exhibiting significant variations as a function of different surface terminations/conditions. The association of these mechanisms with…
