POROUS SILICON MATERIAL

摘要

Provided are a method for producing a porous silicon material filled with a metal, the method comprising the steps of rendering hydrophobic a porous silicon substrate having pores from 1 to 5 nm in diameter, and depositing a metal into the pores of the porous silicon substrate by electroplating the porous silicon substrate; a method for producing metallic nanoparticles and nanofibers, the method comprising the steps of producing the porous silicon material filled with a metal, and dissolving the silicon contained in the porous silicon material filled with a metal; metallic nanoparticles and nanofibers obtained using the method for producing metallic nanoparticles and nanofibers; and a porous silicon material formed from a porous silicon substrate, having pores from 1 to 5 nm in diameter and a resistivity of 5 to 20 O/cm, the pores of which are filled with a metal.
