Abstract

Very short nanofibers containing only a few nanobells have been produced from nitrogen-doped carbon nanotubes by two methods, H-2 plasma treatment, followed by grinding and oxidation with acidified potassium permanganate. The length of these short nanofibers can be controlled to give a wide range of sizes. The shortest nanofibers are composed of only a single nanobell with dimensions of similar to 15 nm in diameter and length. High-resolution transmission electron microscope images reveal that their structures are closed at one end and open at the other. The formation mechanism of these short nanofibers and individual nanobells is discussed along with their potential for interesting nanotube-end physics and chemistry.
