Have you ever wondered how optical nearfields really look like inside of  narrow, sub-wavelength-wide optical nanostructures?  Do they look as expected, or do minor  structure deviations lead to a quite different picture? Here is a method that allows imaging of some special kind of nearfields with t...

There has been research and development on novel electron sources for many decades, for example on sharp metal tips as a source in electron microscopes. These tips are usually electrochemically fabricated and have a minimum tip radius of about 10 nm. For photoemission experiments that exploit the ex...
