Negative refraction of acoustic waves using a foam-like metallic structure

Anne-Christine Hladky, Jerome O. Vasseur, G. Haw, Charles Croënne, L. Haumesser, A.N. Norris

A phononic crystal (PC) slab made of a single metallic phase is shown, theoretically and experimentally, to display perfect negative index matching and focusing capability when surrounded with water. The proposed PC slab is a centimeter scale hollow metallic foam-like structure in which acoustic…

Non-contact air-coupled velocity measurements in planar samples

Qiang Liu, Bogdan Piwakowski, Zoubeir Lafhaj

Non-contact air-coupled technique has been applied to measure ultrasonic velocities in two planar samples, Plexiglas and mortar. Longitudinal waves and mode-converted shear velocities were obtained by three approaches. The obtained velocities were compared with that measured by contact method. The…

Multiple exciton generation and ultrafast exciton dynamics in HgTe colloidal quantum dots

Ali Al-Otaify, Stephen V. Kershaw, Shuchi Gupta, Andrey L. Rogach, Guy Allan, Christophe Delerue, David J. Binks

The investigation of sub-nanosecond exciton dynamics in HgTe colloidal quantum dots using ultrafast transient absorption spectroscopy is reported. The transmittance change spectrum acquired immediately after pumping is dominated by a bleach blue-shifted by ∼200–300 nm from the photoluminescent…
