Abstract

We report here the formation – via a bottom-up approach – of Cu nanoparticles supported on silica substrates as catalysts for the growth of silicon nanowires. The density and the size (3–5 nm) of Cu particles were controlled by exploiting the density and the distribution of surface silanols on both 3D silica nanoparticles and 2D silica thin films. The growth of Si nanowires on such Cu nanoparticles indicates that a critical particle size is needed for the fast growth of silicon nanowires.
