Abstract

A porous silicon structure is stabilized by anodically oxidizing the structure and then subjecting it to chemical functionalization to protect non-oxidized surface regions, preferably in the presence of 1-decene under thermal conditions. This process creates a protective organic monolayer on the surface of the structure, rendering it highly stable.
