Abstract
Cu Nanoparticles on TiN coated silicon substrates were prepared from well‐defined molecular precursors [CuOtBu]4 in non‐aqueous solutions. The formation of nanoparticles takes place via galvanic displacement and allows for the formation of narrowly distributed Cu nanoparticles with controlled size ranging from 8 to 35 nm through the control of the oxidation state of the TiN surface. The activity of these nanoparticles arrays in low temperature Si nanowires growth by the vapor‐solid‐solid mechanism was also investigated and larger Cu nanoparticles were found to yield higher Si nanowires density.
