Anisotropy effects on the time-resolved spectroscopy of the acoustic vibrations of nanoobjects†
Abstract
The impact of spherical symmetry breaking and crystallinity on the response of the vibrational acoustic modes of a nanoobject in frequency- and time-domain experiments is investigated using the finite-element analysis method. The results show that introduction of shape anisotropy, i.e., evolution from a nanosphere to a
