New Science Advances Article


Symbolic image of 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.
Schematic image of the nanofocusing of short-range surface plasmons in the center of concentric ring apertures.
Experimental setup: Plasmon excitation and imaging are realized via two photon photoemission microscopy (2PPE PEEM) at normal incidence. The plasmon excitation wavelength is 800 nm. Electrons are emitted from the plasmon wave and imaged with nanometer resolution using electron optics.
PEEM image of a 22 nm thick single crystalline gold platelet, patterned with a circular grating of 150 nm period via focused ion beam milling. The diameter of the central disk is 2 µm. The short-range plasmon couples into the disk, waves collide at the center, forming an oscillating 60x120 nm² electron hot spot, from which the electrons are emitted.

Our new Science Advances article Short-range Surface Plasmonics: Localized Electron Emission Dynamics from a 60 nm Spot on Atomically Flat Single Crystalline Gold by Bettina Frank, Philip Kahl, Daniel Podbiel, Grisha Spektor, Meir Orenstein, Liwei Fu, Thomas Weiss, Michael Horn-von Hoegen, Tim J. Davis, Frank-Joachim Meyer zu Heringdorf, and Harald Giessen has now been published.
