IBM brings carbon nanotube-based computers a step closer

Helping the hunt for something to replace silicon transistors, Big Blue researchers have found a way to precisely place carbon nanotubes -- or rather, to encourage them to place themselves


IBM isn't promising the technique will be commercially viable, but some optimism shows through in the paper -- in particular because the process is compatible with current chipmaking technology.
"This new placement technique is readily implemented, involving common chemicals and processes, and provides a platform for future CNTFET experimental studies," the paper said. "Furthermore, these results show that CNT placement via chemical self-assembly is a promising approach for developing a viable CNT logic technology compatible with existing semiconductor fabrication."
