Patent ID: 8691011

Claim:
A method of producing nanostructured devices comprising nanowires epitaxially grown over a surface of a substrate, the method comprising the steps of: providing an oxide template on the surface of the substrate, wherein the oxide template forms a nanowire nucleation catalyst layer of SiOx, wherein x≈1; growing the nanowires on the SiOx oxide template on the surface of the substrate, and hydrogen termination of the surface of the substrate in order to temporarily passivate the surface; wherein the step of providing an oxide template comprises a pre-treatment prior to the step of growing nanowires comprising the steps of: applying a thin organic film on the substrate surface; and providing a nucleation onset period, wherein the conditions as regards to time and environment are controlled so that a partial oxidation of the surface of the substrate occurs, the partial oxidation guided at least partly by the applied thin organic film giving a correlation between the structure of the oxide template and the thin organic film.
