Abstract

Raman scattering from the acoustic phonons confied in si nanocrystals is investigated by a microscopic lattice-dynamical calculation. Polarized and depolarized spectra are found to be rather different, indicated from different acoustic phonons. The polarized scattering is more pronounced than the depolarized one. The calculated results are compared with the recent experimental data. The matrix effects are discussed.
