Abstract
A noble metal nanoparticle can be grown on a semiconductor substrate by contacting a predetermined region of the substrate with a solution including noble metal ions. The predetermined region of the semiconductor substrate can be exposed by applying a polymeric layer over the substrate selectively removing a portion of the polymeric layer. The nanoparticles can be prepared in a predetermined pattern. The nanoparticle can be formed with a barrier separating it from another nanoparticle on the substrate; for example, nanoparticle can be located in a pit etched in the substrate. The size and location of the nanoparticle can be stable at elevated temperatures.
