Theory for light emission from a scanning tunneling microscope
We have calculated the rate of light emission from a scanning tunneling microscope with an Ir tip probing a silver film. In the calculation we model the tip by a sphere. We find a considerableExpand

Electron-plasmon and electron-electron interactions at a single atom contact.
The transition from tunneling to contact is investigated by detecting light emitted from Au(111) in a scanning tunneling microscope. Optical spectra reflect single and multielectron processes andExpand

Unidirectional broadband light emission from supported plasmonic nanowires.
Metal nanowires are thought to become key elements in future nanophotonics applications. Here we show that single crystal silver nanowires supported on a dielectric interface behave similar toExpand

Shape effects in the localized surface plasmon resonance of single nanoholes in thin metal films.
We report on the polarization-dependent optical response of elongated nanoholes in optically thin gold films. We measured elastic scattering spectra of spatially isolated ellipsoidal nanoholes withExpand

Unified treatment of fluorescence and raman scattering processes near metal surfaces.
We present a general model study of surface-enhanced resonant Raman scattering and fluorescence focusing on the interplay between electromagnetic effects and the molecular dynamics. Our modelExpand

Approaching the strong coupling limit in single plasmonic nanorods interacting with J-aggregates
We studied scattering and extinction of individual silver nanorods coupled to the J-aggregate form of the cyanine dye TDBC as a function of plasmon – exciton detuning. The measured single particleExpand

Resonance shift effects in apertureless scanning near-field optical microscopy
(Received 23 August 2002; revised manuscript received 7 November 2002; published 14 February 2003) We develop a theory to study apertureless scanning near-field optical microscopy which takes intoExpand

Optical Forces in Plasmonic Nanoparticle Dimers
We present calculations of the optical forces between two metal nanospheres forming a hybridized plasmonic dimer. We consider homo- and heterodimers and investigate different plane wave illuminationExpand

Surface-state Stark shift in a scanning tunneling microscope.
We report a quantitative low-temperature scanning tunneling spectroscopy (STS) study on the Ag(111) surface state over an unprecedented range of currents (50 pA to 6 microA) through which we can tuneExpand

Mode-specific directional emission from hybridized particle-on-a-film plasmons.
We investigate the electromagnetic interaction between a gold nanoparticle and a thin gold film on a glass substrate. The coupling between the particle plasmons and the surface plasmon polaritons ofExpand
