Abstract
The emission current of Pt-coated self-aligned gated tip arrays deviates from FN behavior at current levels above 100 nA/tip. The space charge force on emitting electrons has been calculated for the worst-case scenario in which the electrons are emitted from a single point and travel to the anode along the same trajectory. It is suggested that the current limitation is most likely due to limitation in supply of electrons rather than the space charge effect.
