Abstract:Cap structures capable of sustaining infinite growth by ingestion of C2 fragments to give a carbon nanotube were screened systematically. For this purpose a total of 23,296 IPR cap structures having characteristic tubule vectors of (5~20, 0~10) were generated by the use of net algorithm. Eighteen recurring patterns were found which involve 50 cap structures having tubule vectors (6~11, 5).
