Field emission property of carbon nanotubes and their application to display devices

Carbon nanotubes (CNTs) possess various unique properties such as a needle-like shape with nanometer-size diameter, high mechanical strength, chemical stability and high electrical conductivity, which are advantages as field electron emitters. Dynamic behavior of CNT emitters revealed by field emission microscopy (FEM) and in-situ transmission electron microscopy (TEM) are first presented, and then development of various types of CNT-based field emission devices is reviewed.
