Abstract
A method of forming carbon nanotubes (CNTs) is disclosed. The method includes dispersing a plurality of substantially semiconductor pure carbon nanotube (CNT) seeds on a substrate to provide a seeded substrate, ozonating the seeded substrate to remove defects on end faces of the plurality of substantially semiconductor pure CNT seeds, and growing carbon extensions on the end faces of the plurality of substantially semiconductor pure CNTs seeds to form a plurality of substantially pure CNTs.
