To realize the application of single-walled carbon nanotubes (SWCNTs) in the electronics field, chirality control of SWCNTs is desirable. However, the selective growth of semiconducting versus metallic SWCNTs has not yet been realized, and further improvement of growth techniques is necessary. Therefore, understanding the growth mechanism of SWCNTs remains an important issue. At present, catalytic chemical vapor deposition (CVD) techniques are commonly used for SWCNT growth because they are suitable for mass production at reduced growth temperatures. In this review, studies on SWCNTs synthesized using various metallic catalysts are surveyed and the current understanding of the SWCNT growth mechanism is presented. In addition, the development of low-temperature growth, another important topic for electronics applications, is discussed.
