In situ imaging of field emission from individual carbon nanotubes and their structural damage
(Georgia Institute of Technology, 2002-02-04)
Field emission of individual carbon nanotubes was observed by in situ transmission electron microscopy. A fluctuation in emission current was due to a variation in distance between the nanotube tip and the counter ...
Work function at the tips of multiwalled carbon nanotubes
(Georgia Institute of Technology, 2001-03-19)
The work function at the tips of individual multiwalled carbon nanotubes has been measured by an in situ transmission electron microscopy technique. The tip work function shows no significant dependence on the diameter of ...
