It is a really interesting work. The article, however, did not explain how the nanowires were made. Were they synthesized first and then attached to the wafer or were they deposited as a film and then lithographically defined on the wafer? If latter, then this is simply the extension of the existing semiconductor manufacturing technology.
It's always interesting to read news about the emerging nanotechnology. I wonder who's more advanced? the universities and non-profit research centers or the private sector?
I wonder how's the technology passed from the schools to the private companies? Who will be the first to capitalize on this innovation?
By the way, I didn't see what kind of metal are the wires made of.
