Chipmakers have hoped that carbon "nanotubes" would allow them to continue using thinner wiring as they pack more devices into chips, but no one had demonstrated nanotube wires working on a conventional silicon chip. In a paper published online today by the journal Nano Letters, electrical engineers at Stanford University and Toshiba report using nanotubes to wire a silicon chip operating at speeds comparable to those of commercially available processors and memory.
"This is the first time anyone has been able to show digital signals going through nanotubes at 1 gigahertz [a billion times a second]," said H.-S. Philip Wong, a professor of electrical engineering at Stanford and a co-author of the report. "There had been a lot of expectations that nanotubes could do this, but no experimental proof so far."

"This is a significant step but it is still very much at the proof of concept level," Close said. "The industry has been waiting for this kind of a demonstration to really move forward."

酷評：哎呀，大傢都是做research的，發發paper就好咯。我同意，這的確是significant step，可是，還要move forward？是不是funding有不夠了？呵呵。
