2003 JUN 16 - (NewsRx.com & NewsRx.net) -- Single-molecule switches have the potential to shrink computing circuits dramatically, but new results from the Arizona State University lab that first described how to wire a single molecule between gold contacts now show that laboratory-standard wired molecules have an unavoidable tendency to "blink" randomly.
In the May 30, 2003, issue of Science, Stuart Lindsay and colleagues identified the cause of this blinking behavior as random, temporary breaks in the chemical bond between the wired molecule and the gold contacts, making this particular wired-molecule arrangement unsuitable for electronic circuits.
