EE Times Asia article: Can Nanotubes Take Us Beyond Moore's Law?

MIT’s work on carbon nanotube field-effect transistors validates a promising path towards practical beyond-silicon electronic systems.
Researchers at MIT have succeeded in building a 16-bit RISC-V microprocessor using carbon nanotube transistors using industry-standard design flows and processes and offering 10 times more energy efficiency than silicon microprocessor.
With silicon no longer following historical scaling trends, there’s been considerable research in beyond-silicon nanotechnologies. Carbon nanotube field-effect transistor (CNFET)-based digital circuits offer one approach that promises substantial energy-efficiency benefits, but the inability to perfectly control intrinsic nanoscale defects and variability in carbon nanotubes has precluded the realization of very-large-scale integrated systems.
