The effect of diameter on the properties of nanotubes has come a step closer to experimental verification with the CVD synthesis described here of large‐diameter single‐walled carbon nanotubes (SWNTs). The SWNTs (see Figure) have a preferential orientation, good purity, and average diameter greater than 3 nm. They exist as macroscopic ropes and aggregate into small bundles.
