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 micro-cell and the other process was to grow CNTs on Mo tips in Spindt-type cathode arrays. The former had fairly good consistent emitters with a number of CNTs, whereas the latter showed a few or single CNTs in micro-sized cells could be formed.
China - and we all know this is where the action is (Da Ling, for example - not a successful example but an example, nevertheless!).
It would not surprise me in the least should Canon-Sony-FET's commercial offering be thusly constructed. What would surprise me is the presence of plain old unadulterated Spindt tips! Those do NOT work!! I assume this new offering does. Thus the NECESSITY of something to make it work - CNTs and/or carbon coat. That's my position and I am sticking to it! Till proved wrong.
Another thing that would not surprise me is Canon up to its neck in this, and I do not mean just supplying the IP. I do like surprises, however!!!!
