Canadian and U.S. researchers say they've engineered a minute
electronic circuit, containing two wires separated by the distance
of just 150 atoms. The advances made by a team of scientists from
McGill University and Sandia National Laboratories could have a
significant effect on the speed and power of the ever-smaller
integrated circuits in everything from smartphones to desktop
computers, televisions and GPS devices, a McGill release said
Wednesday.
Unexpectedly, the authors found that in a circuit in which
components are packed so close together, one wire's effect on
another other can be either positive or negative. That means a
current in one wire can produce a current in the other that flows
in either the same or the opposite direction. The researchers say
the discovery suggests scientists' understanding of how electronic
circuits behave at the nanoscale will need to be revised.
