Synthetic routes toward scalable, tunable carbon nanotube ensembles for use in devices
Abstract/Contents
- Abstract
- Studies of carbon nanotube forests, carbon nanotube transistors and wire bundles, and carbon nanotube doping are carried out. A synthesis technique called "synergetic carbon nanotube growth" is developed in which enhanced growth rates are induced in catalyst areas of micron-scale feature size using asymmetric catalyst designs. This technique is used to fabricate carbon nanotube wire bundles with fair alignment which have resistivities of 1.4-2.2 Ohm*cm. Control of the chirality distribution in carbon nanotube growths is attained using alcohol chemical vapor deposition. Spectroscopic measurements and statistical analysis of transistor device measurements show that the semiconducting fraction in carbon nanotube ensembles can be tuned from 69% to 85% by varying growth temperature. The use of a precursor, triethylamine, is demonstrated to achieve in situ nitrogen doping in carbon nanotube growth at levels of approximately 0.2%, measured by X-ray photoelectron spectroscopy measurements and corroborated by Raman spectroscopy measurements. This work shows that mechanistic explanations ascribing to a surface-mediated process of carbon nanotube growth are correct.
