Scientists at IBM have formed another to silicon for the
logic gates on microchips that will make sure the continuing reduction of the
vital digital switching mechanism for at least ten more years.
The IBM breakthrough, first reported in Nature
Nanotechnology & by the New York Times, uses carbon annotates a kind of
molecule that is a substitute to silicon for the making of miniature logic
gates in microprocessors.

Researchers at IBM’s T.J. Watson Research Center in Yorktown Heights, N.Y. have formed a
pattern of carbon nanotubes on the surface of a silicon wafer. The nanotubes
utilized to produce the processors, the report said, are hybrids of silicon
& carbon nano tubes with more than ten thousand working transistors.
Basically carbon nanotubes are solitary sheets of carbon
rolled into a cylindrical form.
In the Nature Nanotechnology paper, the IBM
researchers explained how they were clever to place ultra-small rectangles of
the stuff in usual arrays by placing them in a soapy combination that creates
them soluble in water.
The scientists utilized a procedure explained as “chemical
self-assembly” to generate the decorative array in which the nanotubes stick in
various areas of the surface while other areas are left untouched. That growth
allows them to organize the nanotubes hundred times more thickly than earlier
methods, and necessary step in economical chip developed.
