Abstract
Dot-patterned carbon nanotube (CNT) emitters with excellent field emission properties were fabricated using photosensitive CNT paste. We carried out a parametric study on the compositions and the fabrication processes of the paste, in particular, by ball milling CNTs, which were optimized in terms of dot shapes and their field emission characteristics. The ball milling process improved the field emission current of the dot-patterned CNT emitters several times higher than that of the non-milled paste.
