  • Abstract
    We have shown that in situ tip self-heating by the emitted electron current can be used to make the current-voltage characteristics of microfabricated field emitter tips nearly identical to one another. The resulting improved emission uniformity could make it possible to realize the full potential of field-emission cathodes to produce current densities of the order of 103-104 amps/cm2 averaged over the area occupied by an array.
