Electrical transport property control of single-walled carbon nanotubes by time-programmed plasma CVD

采用程序升温扩散等离子体化学气相沉积法（CVD）成功地生长了窄直径、手性分布的单壁碳纳米管。通过精确地调整单壁碳纳米管的生长时间在几秒的数量级，它被发现，单壁碳纳米管的手性分布变得相当窄。此外，在这样的初始阶段生长的单壁碳纳米管也显示出具有独特的长度分布，并且几乎所有这样的窄长度分布的单壁碳纳米管都非常短（~ 100 nm）。

Narrow-diameter and -chirality distributed single-walled carbon nanotubes (SWNTs) are successfully grown by time-programmed diffusion plasma chemical vapor deposition (CVD). By precisely adjusting a growth time of SWNTs on the order of a few second, it is found that chirality distributions of SWNTs become fairly narrow. Furthermore, the SWNTs grown at such an initial stage are also revealed to have unique length distributions, and almost all of such narrow length distributed SWNTs are very short (～100nm).
