Single-walled carbon nanotubes (SWCNTs) are comprised of fore frontier applications due to their superior chemical, electrical and optical properties. Chirality controlled SWCNT synthesis is progressing very rapidly to surpass the post growth treatment process. So synthesized SWCNTs had more than 1 nm diameter and with very low yield. The band gap of semiconducting SWCNTs increases with decreasing diameter. Narrow diameter distributed SWCNTs possesses fewer chirality and synthesis of such tubes could be an alternative technique to solve the aforementioned problem. We have proposed a technique to address the above issues by utilizing simultaneously deposited Co and W onto SiO₂ as a catalyst. In this research, we will give an insight into ultra-small SWCNTs grown in our system.
