Vertical carbon nanotubes......

Highly ordered, vertical carbon nanotubes (CNTs) have been grown on a pre-patterned, porous anodic aluminum oxide (AAO) template using a lithographic patterning method and thermal chemical vapor deposition. The AAO template itself plays a catalytic role in CNT growth and the crystallinity of the CNTs is strongly influenced by the presence of cobalt particles at the bottom of the template pores (W.B. Choi et al., Feb. 19; Adv. Mater. 2002, 14, 277-279).
