摘要： Zinc-oxide nanostructures are formed by forming a pattern on a surface of a substrate. A catalyst metal, such as nickel, is formed on the surface of the substrate. Growth of at least one zinc oxide nanostructure is induced on the catalyst metal substantially over the pattern on the surface of the substrate based on a vapor-liquid-solid technique. In one exemplary embodiment, inducing the growth of at least one zinc-oxide nanostructure induces growth of each zinc-oxide nanostructure substantially over a patterned polysilicon layer. In another exemplary embodiment, when growth of at least one zinc-oxide nanostructure is induced, each zinc-oxide nanostructure grows substantially over an etched silicon substrate layer.

摘要： A method is provided for patterning iridium oxide (IrOx) nanostructures. The method comprises: forming a substrate first region adjacent a second region; growing IrOx nanostructures from a continuous IrOx film overlying the first region; simultaneously growing IrOx nanostructures from a non-continuous IrOx film overlying the second region; selectively etching areas of the second region exposed by the non-continuous IrOx film; and, lifting off the IrOx nanostructures overlying the second region. Typically, the first region is formed from a first material and the second region from a second material, different than the first material. For example, the first material can be a refractory metal, or refractory metal oxide. The second material can be SiOx. The step of selectively etching areas of the second region exposed by the non-continuous IrOx film includes exposing the substrate to an etchant that is more reactive with the second material than the IrOx.
