Abstract
An electron emission device with nano-protrusions is described. Electrons are emitted from the nano-protrusions and directed by one or more conductors into beams. The beams may be shaped to be collimated, diverged, or converged. The shaped beams from one or more nano-protrusions may be focused onto a target spot through the use of additional electron optics.
