Abstract:
1. A method for manufacturing a carbon nanotube array, the method comprising the steps of: (a) providing a substrate; (b) forming a catalyst layer on the substrate; (c) heating the substrate to a predetermined temperature; and (d) intermittently introducing a reaction gas proximate the substrate to grow a patterned carbon nanotube array, each carbon nanotube having at least one line mark formed thereon as a result of the patterned growth; wherein the intermittent introduction of the reaction gas is executed by repeating a process of providing the introduction of the reaction gas for a first predetermined time and interrupting the introduction of the reaction gas for a second predetermined time, and the interrupting the introduction of the reaction gas includes switching off the introduction of the reaction gas.
