Abstract

We have fabricated a high electron source from carbon nanotubes (CNTs) using hot-press method. Using hot-press method, we are able to control the tube density and the morphology of CNT films. We propose that the high emission current is due to the solid adhesion between the CNTs and substrates and uniform morphology of CNT film.
