Lately, we have tried to obtaine SEM images of porous SiO2 in our
laboratory. It was formed after special treatment with acid for pores
formation. The diameter ranges from 40 to 60nm and the thickness of 6-8µm,
but we did not succeed. The SEM microscope used is Quanta 200. The different
conditions were from 20 to 5kV and spot size from 5-to 1.5.
If you are familiar with this problem we will appreciate your help. Thanks.
