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.
