“Many research teams are working to make electronics that include carbon nanotubes—rolled-up sheets of carbon atoms that have useful electrical properties and that can be as narrow as the span of four hydrogen atoms.
Researchers from the University of California at Berkeley and Stanford University have fabricated a circuit that combines carbon nanotube transistors and traditional silicon transistors on one computer chip. Connecting minuscule nanotube transistors to traditional silicon transistors enables the atomic-scale electronics to communicate with existing electronic equipment.
Such integrated nanotube-silicon circuits could enable super-sensitive sensors that distinguish among thousands of chemical or biological agents and ultra-high-density memory chips that store 100 times the information of today’s state-of-the-art memory chips, according to the researchers.”
