A method for making semiconducting carbon nanotubes is provided. A catalyst precursor is disposed on a substrate. The catalyst precursor includes blood. Organic substances contained in the blood are removed and iron ions contained in the blood are oxidized to yield discrete ferric oxide nano-particles on the substrate. The ferric oxide nano-particles are reduced to yield isolated iron nano-particles on the substrate. Carbon nanotubes then grow on the iron nano-particles.

A method for forming a recess defect on a carbon nanotube is introduced. The method includes the following steps. A substrate with a surface is provided. A first carbon nanotube is deposed on the surface of the substrate. A second carbon nanotube is crossed with the first carbon nanotube. The second carbon nanotube crosses the first carbon nanotube and is in contact with the first carbon nanotube. A mask is deposited on substrate, the first carbon nanotube, and the second carbon nanotube. The substrate is etched to remove the second carbon nanotube and form a recess defect on the first carbon nanotube at a crossing position.
