manufacturing method of carbon nanotube electron emitters for low voltage operation and the carbon nanotube electron emitters manufactured thereby

摘要

invention is used for spraying the CNT electron emission source for the production as in the low voltage drive relates to metal nanoparticles to be added to the carbon nanotube, a binder, and at the same time and this method for producing carbon nanotubes by a field emission device electron emitter for producing. In particular, the binder is cured using a low temperature binder, nor by preparing the binder material and the size and form a stable dispersion solution is controlled by controlling the interaction of the metal precursor over the sol-gel process, the size of the metal nano-particles formed to small and uniform The curing process is advantageous in that it can be implemented with only the firing of the metal nano-particles at the same time with the advantage of shortening the process time, cost and low-voltage driving is possible and can be implemented while the electron-emitting characteristics uniform thin film.
