Chiral-selective etching effects on carbon nanotube growth at edge carbon atoms

We note that chemical vapor deposition using metal cluster nanoparticle catalysts is commonly used to synthesize carbon nanotubes, with oxygen-containing species such as water or alcohol included in the feedstock for improved yield. Using CNT cap models, we investigated how water-based etchant radicals could increase chiral selectivity during CVD growth. Using density functional theory, the reactivities of the caps with the etchant radicals were determined.
