The connection between elastic scattering cross sections and acoustic vibrations of an embedded nanoparticle
L. Saviot, D. B. Murray
Arbitrary waves incident on a solid embedded nanoparticle are studied. The acoustic vibrational frequencies are shown to correspond to the poles of the scattering cross section in…
Acoustic vibrations of a silica-embedded gold nanoparticle: elastic anisotropy
Daniel B. Murray, S. Dhara, T. R. Ravindran +4
Spherical gold nanoclusters are grown by 1.8 MeV Au++ ion implantation into an amorphous silica matrix and subsequent air annealing at 873 K. Ultraviolet and visible light absorpti…
Continuum elastic sphere vibrations as a model for low-lying optical modes in icosahedral quasicrystals
E. Duval, L. Saviot, A. Mermet +1
The nearly dispersionless, so-called "optical" vibrational modes observed by inelastic neutron scattering from icosahedral Al-Pd-Mn and Zn-Mg-Y quasicrystals are found to correspon…
Long lived acoustic vibrational modes of an embedded nanoparticle
Lucien Saviot, Daniel B. Murray
Classical continuum elastic calculations show that the acoustic vibrational modes of an embedded nanoparticle can be lightly damped even when the longitudinal plane wave acoustic i…
