Shortly after reading of MIT’s 100-fold breakthrough in light-gathering capabilities for solar cells, we saw the news about a one-thousand-fold increase claimed by Rice University researchers.  Professor of physics and astronomy Doug Natelson announced the findings of his research group, which includes his graduate student Dan Ward, and colleagues in Germany and Spain. In his blog, Natelson stated, “My student (with theorist collaborators) had a paper published online in Nature Nanotechnology yesterday, and this gives me an excuse to talk about using metal nanostructures as optical antennas. The short version: using metal electrodes separated by a sub-nanometer gap as a kind of antenna, we have been able to get local enhancement of the electromagnetic intensity by roughly a factor of …
