Abstract
A method for growing an array of carbon nanotubes includes the steps of: (a) providing a substrate; (b) forming a catalyst film on the substrate, the catalyst film including carbonaceous material; (c) introducing a mixture of a carrier gas and a carbon source gas flowing across the catalyst film; (d) focusing a laser beam on the catalyst film to locally heat the catalyst to a predetermined reaction temperature; and (e) growing an array of the carbon nanotubes from the substrate.
