abstract = "Porous silicon samples, obtained by electrochemical process in a
solution containing HF-Ethanol were prepared varying etching time
and current density. Using the phonon confinement model the
crystallite size was estimated on the porous layer through the
best fit of the Raman spectrum of first order. The experimental
and theoretical points were better adjusted in order to obtain
more accurate results in relation to previous works. For the
samples with varying the anodization time and keeping constant the
current density the crystallite size had an oscillating behavior
and tendency to decrease as a function of the anodization time.
Varying current density, keeping constant the anodization time,
was observed an increase in the crystallite size as a function
current density.",
