Carbon nanotube (CNT) have a great potential as an electron emitter of the field emission display (FED) due to
their characteristics of high electron emission, rapid response and low power consumption. Recently, a prototype
FED using CNT emitter has been developed and demonstrated. However, in order to commercialize the FED with
the CNT emitter, several fundamental problems regarding the power consumption, life time and emission
efficiency have to be solved. In this study, we investigated the metal nanoparticles-coated CNT as a field emitter
by chemical modification. Ru and Pd nanoparticles were synthesized by polyol process, using a high boiling point
solvent (ethylene glycol)-polyvinylpyrrolidone (PVP) solution to reduce RuCl3 and PdCl2 under reaction temperature
of 160~180�C. Coating of Ru and Pd nanoaprticles on the CNT was conducted by the control of surface
charge. The properties of metal nanoparticles-coated CNT was characterized by TEM, EDX, XRD, XPS, Zeta
potential meter.
