Two kinds of Spindt-type cathode arrays with vertically aligned carbon nanotubes (CNTs) emitters were fabricated. One process involved direct growth of CNTs from the bottom of each cell and the other process was to grow CNTs on Mo tips. The former had fairly good consistent emitters with a number of CNTs that depend on catalyst areas deposited, whereas the latter showed a few or single CNTs in micro-sized cells could be formed.
