This wafer contains tiny computers using carbon nanotubes, a material that could lead to smaller, more energy-efficient processors.
Unprecedented feat points toward a new generation of energy-efficient electronics. A team of Stanford engineers has built a basic computer using carbon nanotubes, a semiconductor material that has the potential to launch a new generation of electronic devices that run faster, while using less energy, than those made from silicon chips. This unprecedented feat culminates years of efforts by scientists around the world to harness this promising but quirky material. The achievement is reported today in an article on the cover of the journal Nature written by Max Shulaker and other doctoral students in electrical engineering. The research was led by Stanford professors Subhasish Mitra and H.-S. Philip Wong. "People have been talking about a new era of carbon nanotube electronics moving beyond silicon," said Mitra, an electrical engineer and computer scientist.
