This is a continuation of the initial experiments testing the possibility of creating porous Si membranes with thicknesses ranging from 50 to several hundred nm, and mean pore diameters from ~50-200 nm. As suggested, we’ve started using 200 µm thick…

We are proposing a novel method for the fabrication of porous thin-film silicon membranes. It has been shown that metallic nanoparticles on the surface of silicon submerged in a solution of hydrofluoric acid and hydrogen peroxide will bore holes into…
