Abstract

In this paper, the fibers were catalytically grown using a chemical vapor deposition method. The graphite nanofiber powder was then ultrasonically dispersed in ethanol. One drop of suspension was put onto a 20-nm thick gold layer deposited on a 1 cm /spl times/ 1 cm silicon substrate and spun to obtain a uniform coating of nanofibers. The fiber density was obtained from SEM images. There was plenty of room between the fibers so that electrostatic screening effects, which occur when field emitter tips or carbon nanotubes are stacked too close together, should not play a significant role in a field emitter testing.
