Dynamics of confined cavity modes in a phononic crystal slab investigated by in situ time-resolved experiments

R. Marchal, Olga Boyko-Kazymyrenko, Bernard Bonello, Jinfeng Zhao, Laurent Belliard, Mourad Oudich, Yan Pennec, Bahram Djafari-Rouhani

The confinement of elastic waves within a single defect in a phononic crystal slab is investigated both experimentally and theoretically. The structure is formed by a honeycomb lattice of air holes in a silicon plate with one hole missing in its center. The frequencies and polarizations of the…

Theory and Monte Carlo simulations for the stretching of flexible and semiflexible single polymer chains under external fields

F. Manca, S. Giordano, Pier Luca Palla, F. Cleri, L. Colombo

Recent developments of microscopic mechanical experiments allow the manipulation of individual polymer molecules in two main ways: uniform stretching by external forces and non-uniform stretching by external fields. Many results can be thereby obtained for specific kinds of polymers and specific…

On the origin of basal stacking faults in nonpolar wurtzite films epitaxially grown on sapphire substrates

Philippe Vennéguès, Jean Michel Chauveau, Z. Bougrioua, Tiankai Zhu, Denis Martin, Nicolas Grandjean

The microstructure of nonpolar heteroepitaxial wurtzite films (GaN and ZnO-based) is dominated by the presence of planar basal stacking faults (BSFs). In this paper, transmission electron microscopy studies of both GaN and ZnO nonpolar films oriented either (11–20) or (1–100) and grown on sapphire…

Microwave On/Off ratio enhancement of GaAs photoconductive switches at nanometer scale

Charlotte Tripon-Canseliet, Salim Faci, Antoine Pagies, Vincent Magnin, Stéphane Formont, Didier Decoster, Jean Chazelas

This paper reports on performances enhancement of photoconductive switches in term of On/Off ratio and insertion losses. The optimization parameters on which the research has been focused are gap dimensions reduction to nanometer scale. The device characterization results up to a microwave…

Métrologie Terahertz des liquides par microsystème microfluidique, Terahertz metrology on liquids in microfluidic microsystem

S. Laurette

Cette thèse présente la conception, la caractérisation et l'utilisation d'un microsystème intégrant des fonctions terahertz (THz) guidées. L'interprétation des mesures conduit à la définition d'une métrologie des liquides aux fréquences THz. Ceci est possible par le…, This work presents the conception, characterization and use of a microfluidic microsystem dedicated to liquid metrology at THz frequencies. First part focuses on developing a versatile and sensitive microsystem, co-integrating microfluidic and THz integrated functions. A glass/polymer/silicon…
