Tilted columnar metal film as transducer of transverse coherent acoustic phonons in picosecond acoustics

A. Chargui, N. Martin, G. Ferro, Arnaud Devos

Picosecond acoustics has been widely used to study thin film elasticity, hypersound attenuation, and adhesion of thin films to substrates. A major limitation of the technique is its restriction to only longitudinal waves. Although work has been reported on the ultrafast generation and detection of…

Quantification and mitigation of the effect of resynchronization errors in ultrasound sensor network for passive imaging in elastic plates

Omar Bouchakour, Emmanuel Moulin, Lynda Chehami, Nikolay Smagin

The problem of signal desynchronization in passive imaging based on noise correlation for defect detection in elastic plates is investigated. Although a post-processing resynchronization process relying on the symmetry of noise correlation functions can be applied prior to the imaging algorithm,…

Terahertz molecular water laser using quantum cascade laser pumping

L. Juppet, Alexandra Khabbaz, J. Lampin, O. Pirali

Molecular lasers pumped by quantum cascade laser (QCL) open new possibilities for THz generation and its numerous applications, in particular, for high resolution molecular spectroscopy. In this article, a THz water laser pumped by a mid-infrared QCL was demonstrated using the broad tunability of…

Surface acoustic wave confinement inside uncorrelated distributions of subwavelength scatterers

Thibault Deletang, Adnane Noual, Bernard Bonello, Roman Buisine, Yan Pennec, Bahram Djafari-Rouhani

We report an experimental study of surface acoustic wave (SAW) localization and propagation in random metasurfaces composed of Al scatters using pump–probe spectroscopy. Thanks to this technique, wideband high frequency acoustic modes are generated, and their dynamical propagation directly from…

Demonstration of avalanche capability in 800 V vertical GaN-on-Silicon diodes

Youssef Hamdaoui, Idriss Abid, Sondre Michler, Katir Ziouche, F Medjdoub

High-quality pseudo-vertical p-n diodes using a GaN-on-silicon heterostructure are reported. An optimized fabrication process including a beveled deep mesa as edge termination and reduced ohmic contact resistances enabled high on-state current density and low onresistance. A uniform breakdown…
