Abstract

We present a method to both precisely and continuously control the average diameter of single-walled carbon nanotubes in a forest ranging from 1.3 to 3.0 nm with ~1 Å resolution. The diameter control of the forest was achieved through tuning of the catalyst state (size, density, and composition) using arc plasma deposition of nanoparticles. This 1.7 nm control range and 1 Å precision exceed the highest reports to date.

摘要

我们提出了一种方法，可精确且连续地控制森林状单壁碳纳米管的平均直径，其范围在1.3至3.0纳米之间，分辨率约为1埃。通过使用纳米颗粒的电弧等离子体沉积来调节催化剂状态（尺寸、密度和组成），实现了对森林状碳纳米管直径的控制。这1.7纳米的控制范围和1埃的精度超过了迄今为止的最高报道。
