MANUFACTURE OF ARTICLE CONTAINING CARBON NANOTUBE AND DEVICE INCLUDING CUT-OFF CARBON NANOTUBE

摘要

PROBLEM TO BE SOLVED: To provide a method for improving emission characteristics of a set of aligned nanotubes. SOLUTION: Emission characteristics of aligned nanotube array 12 are improved by cutting off an end of a nanotube. The nanotube 12 which has a length of not more than 30% of an average cut-off nanotube and has an end substantially without an end cap is provided by cutting off the end. The end without the cap provides a desired electric field convergence, and high uniformity increases the number of contributing nanotubes.
