In this paper, three types of multi walled carbon nanotubes (CNTs) were grown with a conventional method (Type I), resist-assisted patterning (Type II, RAP), and robust (Type III) method. Electron emission current were compared with atmospheric stability of CNTs grown through plasma enhanced chemical vapor deposition. For environmental stability measurements, these samples were annealed in 700 degC furnace up to 10 hr and/or rapid thermal annealing system under ambient environment. The detailed structural changes were evaluated through SEM with various ambient annealing time and relationship to electron emission current.
