ABSTRACT:
A method for forming a carbon nanotube array using a metal substrate includes the following steps: providing a metal substrate (11); oxidizing the metal substrate to form an oxidized layer (21) thereon; depositing a catalyst layer (31) on the oxidized layer; introducing a carbon source gas; and thus forming a carbon nanotube array (61) extending from the metal substrate. Generally, any metallic material can be used as the metal substrate. Various carbon nanotube arrays formed using various metal substrates can be incorporated into a wide variety of high power electronic device applications such as field emission devices (FEDs), electron guns, and so on. Carbon nanotubes formed using any of a variety of metal substrates are well aligned, and uniformly extend in a direction substantially perpendicular to the metal substrate.
