At a meeting yesterday, Chris Newfield suggested that the recent hybrid silicon laser developed by UCSB prof John Bowers was nanotechnology. Because I'm a cantankerous skeptic, I pooh-poohed this (a highly technical term oft used in the social sciences) as hardly being nano. I went back and re-read the press releases such as:
to see if I was right. The process used, according to the press release, involves creating a nanoscale oxide layer.
This raises a good question - When do we call something nanotechnology or nanoscience? By a strict definition, it does or at least part of the manufacturing process does. But even the press release refers to its having been made using "standard silicon manufacturing processes." Nano or no nano?
