研究了由Fe/Al多层催化剂组成的纳米颗粒阵列，通过热化学气相沉积法制备单壁碳纳米管。通过对Fe/Al薄层的退火，可以有效地形成数量密度高、尺寸分布窄（1 ~ 5 nm）的Fe纳米颗粒，从而实现了单壁碳纳米管的高产率生长。此外，我们还发现孤立的单壁碳纳米管来源于Fe/Al岛。桥接在电极之间的SWNTs表现出半导体和金属性质。
We explored the growth of single-walled carbon nanotubes (SWNTs) from nanoparticle array made of an Fe/Al multilayer catalyst by thermal chemical vapor deposition. Fe nanoparticles with a high number density and a narrow size distribution (1–5 nm) were efficiently formed by annealing the Fe/Al thin layer, resulting in the high-yield growth of SWNTs. Moreover, it was found that isolated SWNTs are rooted from patterned Fe/Al islands. The SWNTs bridged between electrodes exhibited semiconducting and metallic properties.
