Abstract:Compared favorably with conventional field emitters made of metal such as molybdenum, CNTs have superiority of field enhancement due to high aspect ratio and durability of emitters due to high thermal conductivity and chemical inertness. Briefly research to fabricate field emitters using CNTs consists of direct-growth and indirect-attachment.Because of vertical alignment and high adhesion force, emitters fabricated by direct-growth generally show better properties of field emission than those fabricated by ind… Show more
