Abstract: A method of growing a carbon nanotube includes the step of impinging a beam of carbon-containing molecules onto a substrate to grow at least one carbon nanotube on the catalyst surface.

Abstract: Vertically aligned carbon nanotubes (VACNTs) of increased length are produced in a method that introduces ferrocene into an acetylene/hydrogen/inert gas stream during a chemical vapor deposition process. The ferrocene is supplied from a controllable thermal sublimation source. Independent and precise control of the ferrocene into the feedstock gas facilitates the growth of thick films comprising long carbon nanotubes on conductive substrates. An order of magnitude increase in the length of CNTs, from a few hundred microns to several mm is achieved.

Abstract: A method is described for catalyst-induced growth of carbon nanotubes, nanofibers, and other nanostructures on the tips of nanowires, cantilevers, conductive micro/nanometer structures, wafers and the like. The method can be used for production of carbon nanotube-anchored cantilevers that can significantly improve the performance of scaning probe microscopy (AFM, EFM etc). The invention can also be used in many other processes of micro and/or nanofabrication with carbon nanotubes/fibers. Key elements of this invention include: (1) Proper selection of a metal catalyst and programmable pulsed electrolytic deposition of the desired specific catalyst precisely at the tip of a substrate, (2) Catalyst-induced growth of carbon nanotubes/fibers at the catalyst-deposited tips, (3) Control of carbon nanotube/fiber growth pattern by manipulation of tip shape and growth conditions, and (4) Automation for mass production.
