Time-Resolved Phonon Spectroscopy and Phonon Transport in Nanoscale Systems,nable acoustic source in GHz–THz frequency range which is excited by using ultrafast pulse shaping technique. Frequency-dependent mean-free-path and group velocity directly at the frequency range where phonon wavelength becomes comparable to the size of the nanoscale materials.
