文摘
Continued growth is a way of growing nanotubes targeted to produce continuous and chirality-controlled single-walled carbon nanotube(SWNT) materials. This growth method strongly depends on efficient preparation of open-ended SWNT substrates. Nanoscopically flat open-ended SWNT substrates have been prepared by cutting the SWNT spun fiber with a focused ion beam cutting technique and followed byetching schemes for cleaning amorphous carbon and opening the ends of the SWNTs. The open ends were effectively characterized throughselective etch back of open SWNT ends by carbon dioxide gas at 950
