Abstract
Helium and Gallium-ion beam milling in combination with a fast and reliable Sketch-and-peel technique is used to fabricate pairs of gold nanoantennas with a superior quality factor and with gap distances down to 6nm. The high fabrication quality compared to standard ion beam milling is proven by polarization-resolved dark-field spectro-microscopy of isolated nanoantennas pairs. We observe a strong coupling of the two antenna arms for both fabrication techniques, however with an outstanding quality factor for the Sketch-and-peel-produced antennas. The presented fabrication technique can pave the way to the production of plasmonic nanostructures on large spatial scales with high milling accuracy.
