摘要

presented a novel method which allows the characterization of diameter selective phenomena in SWCNTs. It is based on the transformation of fullerene peapod materials into double-wall carbon nanotubes and studying the diameter distribution of the latter. The method is demonstrated for the diameter selective healing of nanotube defects and yield from C70_{70} peapod samples. Openings on small diameter nanotubes are closed first. The yield of very small diameter inner nanotubes from C70_{70} peapods is demonstrated. This challenges the theoretical models of inner nanotube formation. An anomalous absence of mid-diameter inner tubes is observed and explained by the suppressed amount of C70_{70} peapods due to the competition of the two almost equally stable standing and lying C70_{70} peapod configurations.
