Abstract
A method of fabricating a carbon nanotube ('CNT') array includes providing a substrate with a CNT catalyst disposed on a surface of the substrate, heating the CNT catalyst to an annealing temperature, exposing the CNT catalyst to a CNT precursor for an exposure period to pre-load the CNT catalyst, and exposing the pre-loaded CNT catalyst to a carbon source for a growth period to form the CNT array. The formed CNT array comprises a plurality of CNT bundles that are aligned with one another in an alignment direction. At least one of the plurality of bundles comprises an average structural factor of 1.5 or less along an entirety of the length thereof.
