Detection of shorter-than-skin-depth acoustic pulses in a metal film via transient reflectivity
K. J. Manke, A. A. Maznev, C. Klieber +6
The detection of ultrashort laser-generated acoustic pulses at a metal surface and the reconstruction of the acoustic strain profile are investigated. A 2 ps-long acoustic pulse ge…
Intrinsic to extrinsic phonon lifetime transition in a GaAs-AlAs superlattice
Felix Hofmann, Jivtesh Garg, Alexei A Maznev +5
We have measured the lifetimes of two zone-center longitudinal acoustic phonon modes, at 320 GHz and 640 GHz respectively, in a 14 nm GaAs / 2 nm AlAs superlattice structure. By co…
Interaction of a Contact Resonance of Microspheres with Surface Acoustic Waves
N. Boechler, J. K. Eliason, A. Kumar +3
We study the interaction of surface acoustic waves (SAWs) with the contact-based, axial vibrational resonance of 1 μm silica microspheres forming a two-dimensional granular crystal…
