From: Nanowire-supported plasmonic waveguide for remote excitation of surface-enhanced Raman scattering
(a) An optical image of the plasmonic waveguide in a single Au nanowire. (b, c) An SEM image of a Au nanowire and the corresponding emission intensity with various incident polarizations. (d, e) An SEM image of another Au nanowire with a different geometric shape of the terminal and the corresponding emission intensity with various incident polarizations (blue arrow in a).
