Following up on my previous comments for using nanotubes
as ballistic electron field emitters:

It looks like you would have to put the nanotube emmitter
under a fairly high electric field. I'm wondering if
the net effect of the "heat" (which I tend, perhaps
incorrectly to view as the vibration of the nuclei)
gets effectively coupled to the electrons at the tip
of the nanotube and what effectively happens is that the
electrons that get accelerated down the tube are
those are those that have managed to pick up the
greatest amount of thermal energy. If anyone knows
precisely what theories couple atomic vibrational energy to
electron energy I'd like to be pointed at them.
Thanks,
Robert
