A new design for electronics?
The present types of materials and circuits used as the basic pieces of computers have been successively honed and reduced in size over the years and we have gotten ever faster computers. But the present technology is approaching some fundamental limits and scientists have been hard at work looking for new approaches to computer circuitry. The New York Times reports on some of the ideas:
The reason that many computer scientists are pursuing this goal is that the shrinking of the transistor has approached fundamental physical limits. Increasingly, transistor manufacturers grapple with subatomic effects, like the tendency for electrons to “leak” across material boundaries. The leaking electrons make it more difficult to know when a transistor is in an on or off state, the information that makes electronic computing possible. They have also led to excess heat, the bane of the fastest computer chips.
