由於奈米碳管具有極高的縱橫比與極小的尖端曲率半徑，因此奈米碳管有著超乎常態的電子場發射特性，低的場發射起始電壓與大的場發射電流密度，使其為電子場發射平面顯示器的良好材料。
在本論文中，以電弧放電法成長奈米碳管。探討奈米碳管的電子場發射特性，同時並探討成長速率與場發射特性的關係，找出成長良好之電子場發射特性的奈米碳管之最佳化成長參數。使用此最佳化成長參數，大量生產奈米碳管。
同時使用網版印刷的厚膜技術，來製備奈米碳管的電子發射源。因此，奈米碳管容易被埋在所調配之網印漿料中，而無法裸露於表面。為了使得奈米碳管裸露於表面，因此使用電漿蝕刻技術來處理試片表面。於不同的網印漿料中各發現一最佳化的電漿蝕刻條件。其中，場發射起始電壓低於1V/m，場發射電流密度大於6000A/cm2。顯示奈米碳管極具場發射平面顯示器應用之潛力。

Due to their high aspect ratios and small tip radii of curvature, carbon nanotubes possess marvelous electron field emission properties, viz. low turn-on voltage (E0) and large emission current density (Je), and have good potential for using as materials in electron emitters of flat panel display.
In this work, we use the technology of DC arc-discharge to grow carbon nanotubes. The optimal grow condition is based on the study of the field emission characteristic of carbon nanotubes, and the relationship between the rate of grow carbon nanotubes and the field emission characteristic of carbon nanotubes. Using this optimal grow condition, it is easy to produce a great mass carbon nanotubes.
We use the screen printing technology to fabricate the carbon nanotube field emitters. Science carbon nanotubes are always buried in paste, in order to expose their tips, a Ar plasma treatment is conducted to polish sample surface. The optimal condition of Ar plasma dry etching is found for different pastes. As a result, the turn on voltage is lower than 1V/m, and the field emission current density is larger than 6000A/cm2.
