| 摘 要： | 以乙腈为碳源,二茂铁为催化剂,用化学气相沉积（CVD）法,制备了薄壁开口定向氮掺杂的多壁碳纳米管。在780℃～860℃的生长温度范围内,随着温度的升高,碳纳米管的场发射效应增强。当生长温度为860℃时,制备碳纳米管的开启电场为0．27V／μm,阀值电场为0．49V／μm,增强因子为1．09×10^5。与其他材料相比,这种碳纳米管体现了非常优越的场发射性能。

| Abstract: | Thin- walled, open- ended, aligned and N- doped multi- walled carbon nanotubes（CNTs） were synthesized using acetonitrile as carbon source, ferrocene as catalyst by chemical vapor deposition（CVD） method. It is found that the field- emission properties become better as the growth temperature rises in the range of 780--860℃.When the growth temperature is kept at 860℃ the turn-on field is 0.27V/μm, threshold field 0.49V/μm, field- enhancement factors 1.09× 10^5. Compared with other materials, this kind of CNTs show outstanding field- emission properties. |
