    Intrinsic damping in metal nanoparticles
    Caruso, Noe Angelo ( 2015)
    Micro-scale mechanical resonators typically exhibit quality factors in the tens of thousands, while those of nanoscale devices are considerably smaller. This thesis is a study of the damping measured using ultrafast laser measurements of metal nanoparticles. Continuum, quantum, and molecular approaches are used to investigate the origins of observed damping. Together these approaches provide evidence that acoustic damping in metal nanoparticles is dominated by phonon-phonon interactions.
