Claim Text:
1. A method for fabricating a plurality of carbon nanotube structures, the method comprising: providing a substrate; forming a non-catalytic metal layer on the substrate, where the non-catalytic metal layer is formed to have a thickness of from about 0.6 nm to about 2.0 nm; forming a catalytic metal layer on the non-catalytic metal layer; depositing and patterning a layer of a resist material for forming a pattern in the catalytic metal layer; removing the remaining resist material the pattern in the catalytic metal layer is formed; subjecting the catalytic metal layer to an ultrasonication and exposure to water step, the ultrasonication and exposure to water step comprising: after the ultrasonication and exposure to water step, forming the plurality of carbon nanotube structures on the substrate in the presence of the catalytic metal layer, wherein the ultrasonication and exposure to water step is a step that is separate from the remaining resist removing step and occurs after the remaining resist material removing step and immediately prior to the carbon nanotube forming step.
