image: This image symbolizes the experimentally measured snapshots at different times for short-range surface plasmons (excited with light at 800 nm wavelength, the electron waves on a single crystalline, atomically flat gold surface), the nanofocus in the center which is created, and the electrons ejected by the nanofocus. This material relates to a paper that appeared in the July 12, 2017, issue of Science Advances, published by AAAS. The paper, by B. Frank at University of Stuttgart in Stuttgart, Germany, and colleagues was titled, 'Short-range surface plasmonics: Localized electron emission dynamics from a 60-nm spot on an atomically flat single-crystalline gold surface.' view more
