Abstract

Carbon nanotubes (CNTs) have used as an electron field emitter of the field emission display (FED) due to their characteristics of high-electron emission, rapid response and low power consumption. However, to commercialize the FED with CNT emitter, some fundamental problems regarding life time and emission efficiency have to be solved. In this study, we investigated the metal coated CNT as a field emitter on which metal nanoparticles were coated by chemical modification. Metal nanoparticles, such as Ru, Pd, were synthesized by solution reduction method. The size of the metal nanoparticle has the range of 2 - 5 nm. Surface was modified chemically with the use of ionic surfactant which changed the surface charge of nanoparticles.
