A method for fabrication of carbon nanotube field emitter using the sol-gel coating and nano-fissure formation technique

摘要

The present invention is to heat the carbon nanotube-gel thin film made by coating the electrode in order to improve the adhesion between the electrode and the carbon nanotubes using carbon nanotube-sol to prevent the electric field emission characteristic degradation and to improve the uniformity of electron emission It describes a method for producing carbon nanotube field emitters using carbon nanotubes that make nanocracks and expose them between cracks. Method for producing a carbon nanotube field emitter through a carbon nanotube-gel thin film according to the present invention, preparing a carbon nanotube-sol for forming a carbon nanotube-gel thin film; Coating the carbon nanotube-sol on the electrode by using a sol-gel coating method to form a carbon nanotube-sol thin film; Forming a carbon nanotube-gel thin film through vacuum drying; And exposing the clean carbon nanotubes between the nanocracks generated when the carbon nanotube-gel thin film formed on the electrode is heated, thereby producing a carbon nanotube field emitter, whereby the carbon nanotube electrode At the same time, clean carbon nanotubes are uniformly exposed on the electrode surface and have uniform electron emission characteristics.;Carbon nanotube, sol-gel coating, field emitter, electron emission, FED
