Abstract

The growth of silicon nanotubes (SiNTs) by a dual-RF-plasma treatment technique is reported here. These SiNTs are vertically aligned and self-assembled from Si substrates at 500 degree Celsius by the use of Cu catalysts. Their diameters are ∼50 to 80 nm with tubular wall thickness of ∼10-15nm. Cu vapors were found partially filled inside the SiNTs. This is a novel technique that can convert bulk materials into their nanostructures.
