TL;DR: In this paper, a core-shell GaAs/AlGaAs nanowire photodetector operating at room temperature was demonstrated, where built-in electric fields at the semiconductor heterointerface and at the metal/semiconductor Schottky contact promote photogenerated charge separation.

TL;DR: Tunable light is generated at an intensity of approximately 200 W/cm(2) as electrons with energies in the 20-40 keV range are injected into gold-silica well structures with a lateral size of just a few hundred nanometers.

TL;DR: The combined use of optical dark-field microscopy, cathodoluminescence, and electron energy-loss spectroscopy to study localized surface plasmons on individual gold nanodecahedra provides useful insight into the complex nature of plasmon resonances in nanoparticles with pentagonal symmetry.

TL;DR: A pair of coupled gold nanorods excited by a beam of free electrons acts as a transmitting Hertzian antenna in the optical part of the spectrum and significantly enhanced resonant emission is observed.

TL;DR: In this article, the reflection spectra of cesium atoms in close vicinity of a nanostructured metallic meta-surface were analyzed and it was shown that the hyperfine sub-Doppler spectrum of the 62S1/2-62P3/2 resonance transition at 852 nm is strongly affected by the coupling to the plasmonic resonance of the nanostructure.
