Quantum Cells Make a Bid To Outshririk Transistors

摘要

Electrical engineers are heading straight for a bruising encounter with the laws of physics as they continue to shrink transistors. Even the most gung-ho circuit builders know that heat overload and quantum effects, such as the elusive behavior of electrons on very small scales, will eventually stop them from packing more and more transistors onto, a single computer chip. But 6 years ago, a pair of electrical engineers, Craig Lent and Wolfgang Porod at the University of Notre Dame in Indiana proposed a scheme for dodging those limits--even exploiting them.
