Description: 
The stress in porous silicon during exposition to a liquid is investigated by an approach based on Raman scattering. When the porous silicon structure is exposed to isopropanol or ethanol, a reversible blue shift of the Raman spectra is observed. The blue shift of Raman scattering is ascribed to the contraction induced by the liquids that fill the pores.
