Hi, I suppose that there is on top of the pillar the deposition of a metal in order to have the plasmonic effects ?

In this case, perhaps it's as you said, only a question of process and the condition of the subsequent measurements, the applications,...

Best regards, Bernard

Hi, the use of Si pillars is more interesting for SERS applications than SiO2, because the refractive index of Si is high and assures a strong confinement of electromagnetic field (EM). SERS effect is strongly dependent on EM field. I hope that this will help you.
