Stanford University researchers design the first GHz chip using carbon nanotubes Shane McGlaun (Blog) - February 15, 2008 3:10 PM DailyTech
Carbon nanotubes are being used in all sorts of research thanks to their strength and much higher electron mobility. Scientists are looking to carbon nanotubes as a replacement for copper wire in circuits, seen to be a bottleneck in future chips.
The problem with using carbon nanotubes in circuits to date has been the difficulty in getting the nanotubes to align correctly on the chips for functional operation. A group of researchers at Stanford University believe they have solved the problem of alignment.
The researchers have developed the world’s first CMOS circuit using carbon nanotubes as an interconnect. The project, carried out in cooperation with Toshiba, fabricated a chip with 256 ring oscillators and 11,000 transistors that operates at 1GHz. [DailyTech...] [Comments...]
