Carbon nanotube-based transistors will take the place of silicon-based transistors in the years following 2020, according to IBM. The 5-nanometer process node will likely be the end of the line for silicon chips, the company predicts. "That's where silicon scaling runs out of steam, and there really is nothing else," IBM's Wilfried Haensch said. IBM researchers have been making carbon nanotube transistors since 1998.
