Patterned deposition of nanotubes is important for electronic devices. With
selected-area deposition of catalyst, nanotubes have been grown as a forest of vertically-aligned nanotubes (Courtesy of Dr. Cattien V. Nguyen, NASA Ames).

Single-walled CNTs can be considered as a flat graphene sheet cylindrically rolled into a tube. The tubes consist of two regions: the sidewall of the tube (along sheet), and the end regions of the tube (top and bottom)(Ahwahnee Technology)1.
