Abstract: The present invention relates to gated nanorod field emission devices, wherein such devices have relatively small emitter tip-to-gate distances, thereby providing a relatively high emitter tip density and low turn on voltage. Such methods employ a combination of traditional device processing techniques (lithography, etching, etc.) with electrochemical deposition of nanorods. These methods are relatively simple, cost-effective, and efficient; and they provide field emission devices that are suitable for use in x-ray imaging applications, lighting applications, flat panel field emission display (FED) applications, etc.

Abstract: In some embodiments, the present invention is directed to nanoporous anodized aluminum oxide templates of high uniformity and methods for making same, wherein such templates lack a AAO barrier layer. In some or other embodiments, the present invention is directed to methods of electrodepositing nanorods in the nanopores of these templates. In still other embodiments, the present invention is directed to electrodepositing catalyst material in the nanopores of these templates and growing nanorods or other 1-dimensional nanostructures via chemical vapor deposition (CVD) or other techniques.
