Published Date: May 7, 2008 Copper nanowires grown by new process create long-lasting displaysA new low-temperature, catalyst-free technique for growing copper nanowires has been developed by researchers at the University of Illinois. The copper nanowires could serve as interconnects in electronic device fabrication and as electron emitters in a television-like, very thin flat-panel display known as a field-emission display.
