IBM scientists are reporting progress in a chip making technology that is likely to ensure the shrinking of the size of the basic digital switch at the heart of modern microchips for more than another decade.
The advance, first described in the journal Nature Nanotechnology on Sunday, is based on carbon nanotubes, exotic molecules that have long held out promise as an alternative material to silicon from which to create the tiny logic gates that are now used by the billions to create microprocessors and memory chips.
