SUBSTRATE WITH SUBSTANTIALLY VERTICALLY ALIGNED CARBON NANOTUBES

摘要

An object of the present invention is to provide a substrate with approximately vertically aligned carbon nanotubes, the carbon nanotubes configured to have excellent transferability and be able to transfer a carbon nanotube layer that is more uniform in thickness than ever before. Disclosed is a substrate with approximately vertically aligned carbon nanotubes, wherein the carbon nanotubes are approximately vertically aligned on the substrate, and wherein, at the substrate side rather than the middle part of the longitudinal direction of the carbon nanotubes, there is a part where the number density of the carbon nanotubes in an approximately parallel plane to the substrate, is smaller than that in other parts.
