Nanobelt‐Templated Growth of Carbon Nanotube Rows

Rows of aligned carbon nanotubes standing shoulder by shoulder (see Figure) have been synthesized by growing nanotubes inside Au micro‐ and nanotrenches created by nanobelts or nanowires. This simple non‐lithographic method can be used to fabricate nanotube rows with a width of less than 2 μm, and a length over hundreds of micrometers.
