Quartic scaling of sound attenuation with frequency in vitreous silica
P. -J. Wang, A. Huynh, T. -C. Hung +8
Many theories predict a quartic acoustic attenuation increase at sub-THz frequencies in glassy media for the excess vibrational modes known as the boson peak anomaly. Here by intro…
Direct measurement of coherent subterahertz acoustic phonons mean free path in GaAs
Romain Legrand, Agnès Huynh, Bernard Jusserand +2
Phonon mean free path is generally inferred from the measurement of thermal conductivity and we are still lacking precise information on this quantity. Recent advances in the field…
Sub-Terahertz Monochromatic Transduction with Semiconductor Acoustic Nanodevices
Agnes Huynh, Bernard Perrin, N. D. Lanzillotti Kimura +3
We demonstrate semiconductor superlattices or nanocavities as narrow band acoustic transducers in the sub-terahertz range. Using picosecond ultrasonics experiments in the transmiss…
