大规模（~ 109个原子）的数值模拟表明，等离子体控制的碳原子在衬底和纳米管表面之间的动态传递和再分配能够实现超长单壁碳纳米管（SWCNTs）的生长，并解释了在后期缓慢生长的常见实验观察。结果表明，等离子体工艺的生长速率比等效的中性气体系统高出两个数量级，并且更适合在低纳米器件友好温度下合成swcnts。大规模（~ 109个原子）的数值模拟表明，等离子体控制的碳原子在衬底和纳米管表面之间的动态传递和再分配能够实现超长单壁碳纳米管（SWCNTs）的生长，并解释了在后期缓慢生长的常见实验观察。结果表明，等离子体工艺的生长速率比等效的中性气体系统高出两个数量级，并且更适合在低纳米器件友好温度下合成swcnts。
Large-scale (∼109 atoms) numerical simulations reveal that plasma-controlled dynamic delivery and redistribution of carbon atoms between the substrate and nanotube surfaces enable the growth of ultralong single walled carbon nanotubes (SWCNTs) and explain the common experimental observation of slower growth at advanced stages. It is shown that the plasma-based processes feature up to two orders of magnitude higher growth rates than equivalent neutral-gas systems and are better suited for the SWCNT synthesis at low nanodevice friendly temperatures.Large-scale (∼109 atoms) numerical simulations reveal that plasma-controlled dynamic delivery and redistribution of carbon atoms between the substrate and nanotube surfaces enable the growth of ultralong single walled carbon nanotubes (SWCNTs) and explain the common experimental observation of slower growth at advanced stages.
