A transparent electrode can include a graphene sheet on a substrate, a layer including a conductive polymer disposed over the graphene sheet, and a plurality of semiconducting nanowires, such as ZnO nanowires, disposed over the layer including the conductive polymer.

Nanowire-modified graphene and methods of making and using same

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.
