Paper Abstract

The influences of some parameters of carbon nanotube films on their electronic emission are studied in this paper. A model for the films is set up, and applied to the study. Therefore, the external electric field outside the surface, electric field enhancement factor, and optimum nanotube density of the films are explored and exprssed by analytic equations. The theoretical analyes show that the field enhancemetn factor is senstiive to nanotube denstiy, so the electron emission of the films can be improved at the specific and optimum density, and that the films composed of thinner nanotubes with small resistance should have superior emitting properties, whatever nanotube length is. The resutls obtained here are in good agreement with the relative experiments.
