Periodic nanometer‐scale patterning of sub‐100 nm catalyst particles on silicon is used to grow carbon nanotubes via chemical vapor deposition from methane. The resulting structures consist of very straight individual single‐walled carbon nanotubes that are preferentially aligned along perpendicular directions in the plane (see figure).
