Abstract

We carry out molecular dynamics simulations on heat conduction in nano-porous Si. Phonon dispersion curves are calculated by time-space 2D FFT, and the density of state of phonon is calculated by FFT of autocorrelation of velocity. As the results, both the phonon group velocity and the density of state of phonon of nano-porous Si are reduced than those of single crystal of Si. Thermal conductivity is reduced by not only the artificial short mean free path of phonon but also the reduction of phonon group velocity and the reduction of density of state of phonon.
