Growth of well-aligned carbon nanotube arrays on silicon substrates using porous alumina film as a nanotemplate

Aligned, open-tipped carbon nanotube arrays of high density and uniformity were synthesized via a flame method on silicon substrates using a nanoporou s template of anodized aluminum oxide from which the nanotubes were grown. The diameter and length of the nanotubes are controlled by the geometry of the aluminum oxide template. These results show the feasibility of integrat ion between carbon nanotube arrays and silicon microelectronics. (C) 2001 A merican Institute of Physics.
