Porous silicon (PS) represents the prospective template for the fabrication of metal/PS nanostructures. However n+‐type Sb doped Si Czochralski wafers widely used to fabricate PS may contain resistivity striations and as‐grown microdefects with specific spiral distribution which influence Si dissolution during the formation of PS by anodizing. This may strongly affect on the PS microstructure and...
The application of porous silicon as a template for the fabrication of nanosized copper objects is reported. Three different types of nanostructures were formed by displacement deposition of copper on porous silicon from hydrofluoric acid-based solutions of copper sulphate: (1) copper nanoparticles, (2) quasi-continuous copper films, and (3) free porous copper membranes. Managing the parameters of...
