Features of the Semiconductor Surface structure containing silver particles on the porous Silicon Film Surface Formed by Metal-Assisted Etching

Studying Silver Nanoparticles Deposited on Surfaces of Porous Silicon and a Single Crystal by Chemical Means

“…The predominant deposition of Ag particles on the tips of silicon crystallites could be due to the stronger electric field. A similar situation was observed in [6].…”

“…Due to preliminary etching in an aqueous solution of KOH, the surface of the wafer had a textured relief. A similar silicon wafer with a porous film of silicon, formed via metal-stimulated etching according to the technique described in [6], was used to manufacture sample 2.…”

“…A drop of the solution was applied to the substrate surface and held there for 20 s on both samples. A similar technique was used in [6].…”
