Abstract

Raman scattering line shapes have been calculated for 2D and 3D phonon confinements in porous silicon. The anisotropy of the optical phonon propagation was taken into account for Si, by using realistic phonon dispersion curves obtained by neutron scattering. The theoretical Raman spectra have been compared to the experimental results, and the prevailing nanocrystalline shapes and characteristic dimensions of wire- or sphere-like Si nanocrystallites in porous silicon were estimated.
