TL;DR: Experimental evidence is provided that the intensity elastically scattered off the object scales with the fourth power of the local field enhancement provided by the antenna, and that the underlying electromagnetic mechanism is identical to the one commonly accepted in surface-enhanced Raman scattering.

TL;DR: Using a tapered two-wire transmission line, researchers experimentally focused mid-infrared energy to a nanoscale confined spot with a diameter of 60 nm at the taper apex as discussed by the authors.

TL;DR: Scattering-type near-field optical microscopy is used to map the spatial field distribution of Fano modes in infrared plasmonic systems, observing in real space the interference of narrow (dark) and broad (bright) plAsmonic resonances.

TL;DR: By spectrally matching both modes, their interference yields an enhancement or suppression of the near fields at specific locations, which could be useful in nanoscale coherent control applications.

TL;DR: In this article, the authors reported the fabrication of single electron transistors (SETs) by feedback-controlled electromigration of palladium and palladium-nickel alloy nanowires.
