- 論文の詳細を見る
A novel density control with a structure of an intermixture of long and short carbon nanotubes (CNTs) is first obtained by precisely controlling pretreatment time and hydrogen content. This unique structure of CNTs is probably due to the uniform distribution of large and small iron nanoparticles under optimum pretreatment condition. Scanning electron microscopy is performed to confirm the morphology of catalytic nanoparticles after pretreatment. The obtained results show that a low turn-on field (${\sim}2.2$ V/μm) and an ultra high field emission current density (0.4 A/cm2 at 6.46 V/μm) can be achieved through this novel structure of CNTs.
