Extraction of statistical properties of the point source response of a reverberant plate and application to parameter estimation (L)

Emmanuel Moulin, Hossep Achdjian, Jamal Assaad, Najib Abou Leyla, Karl Hourany, Youssef Zaatar

The point source response of a reverberant solid plate is modeled through a nonstationary Poisson process based on the image-source method. The theoretical expectation of the envelope is then derived, taking into account the dispersive nature of plate waves, and validated by numerical results.…

Effect of phonon confinement on the dispersion relation and heat capacity in nanoscale Si membranes

J. Cuffe, E. Chávez, A. Shchepetov, P.O. Chapuis, E.H. El Boudouti, F. Alzina, Yan Pennec, Bahram Djafari-Rouhani, M. Prunnila, J. Ahopelto, C.M. Sotomayor Torres

The effect of confinement on the acoustic phonon dispersion relation and heat capacity in free-standing silicon membranes is investigated, with thickness values down ∼ 8 nm. The discrete phonon branches are observed by angle-resolved inelastic light scattering spectroscopy. The fundamental flexural…

Loosening quantum confinement : observation of real conductivity caused by hole polarons in semiconductor nanocrystals smaller than the Bohr radius

Ronald Ulbricht, Joep J. H. Pijpers, Esther Groeneveld, Rolf Koole, Celso de Mello Donega, Daniel Vanmaekelbergh, Christophe Delerue, Guy Allan, Mischa Bonn

We report on the gradual evolution of the conductivity of spherical CdTe nanocrystals of increasing size from the regime of strong quantum confinement with truly discrete energy levels to the regime of weak confinement with closely spaced hole states. We use the high-frequency (terahertz) real and…

THz power divider circuits on planar Goubau lines (PGLs)

A. Treizebre, Simon Laurette, Yansheng Xu, Renato G. Bosisio, Bertrand Bocquet

Terahertz spectroscopy is a new tool for real time biological analysis. Unfortunately, investigations on aqueous solutions remain difficult and need to work on nanovolumes. Integrated Terahertz instrumentation remains a challenge. We demonstrate that Planar Goubau Line (PGL) technology could bring…

Corrugated Goubau lines to slow down and confine THz waves

Simon Laurette, A. Treizebre, Bertrand Bocquet

Corrugations on planar Goubau lines are presented in order to slow down and focus electromagnetic waves. A propagation effective index shift is observed between corrugated and non-corrugated planar Goubau lines. Influence of the corrugation geometrical parameters is studied. Two original methods…
