Abstract :
The field emission cathode was fabricated using mized compound of carbon nanotube and insulator. High field enhancement factor ß can be obtained by using distributed carbon nanotubes in the insulating mateial. The turn on field of lower than 5 V/μm was detected for the sample prepared by using sol-gel method.
