Abstract
We report the selective growth of bulk single-walled carbon nanotube (SWCNT) samples enriched with three different dominant chiralities including (6,5), (7,5), and (7,6) through adjusting the pressure of carbon monoxide on Co-Mo catalysts from 2 to 18 bar. Semiconducting SWCNT abundance was evaluated via photoluminescence, optical absorption, and Raman spectroscopy based on a single-particle tight-binding theoretical model, indicating that the abundance of each chiral tube can be systematically altered by changing the carbon monoxide pressure.
