## Abstract

Porous silicon has been shown to have fractal morphology below a certain length scale. Using iow frequency Raman Scattering, we report the kacton dimension d which characterises the vibrational density of states. q(w)$\sim w^{(\v{d}-1)}$. of the fractal network. Taking the Hausdorff dimension D to be 2.5, the value of d obtained is equa1 to $1.42\pm.02,$ which is close to the theoretically predicted value of 4/3.
