ATOM-DRAGGING IMPLICATIONS 'REMARKABLE'
|
NEW YORK - Scientists report they have moved atoms one at a
time to make patterns with great precision, an "absolutely
fascinating" step that could lead to creating new materials and
making computers work even faster.
In a process like dragging ping pong balls across the bumpy
bottom of an egg carton, atoms were arranged in one experiment to
form the letters "IBM," with the design 660 billionths of an inch
long.
Donald Eigler and Erhard Schweizer, who did the work at IBM's
Almaden Research Center in San Jose, Calif., describe the results
in today's issue of the British journal ...
