TLDR
From monolayer films of carbon-60 fullerenes on gold(110) surfaces, intense emission is observed when the STM tip is placed above an individual molecule, demonstrating the highest spatial resolution of light emission to date with a scanning probe technique.Abstract:
The tip-surface region of a scanning tunneling microscope (STM) emits light when the energy of the tunneling electrons is sufficient to excite luminescent processes. These processes provide access to dynamic aspects of the local electronic structure that are not directly amenable to conventional STM experiments. From monolayer films of carbon-60 fullerenes on gold(110) surfaces, intense emission is observed when the STM tip is placed above an individual molecule. The diameter of this emission spot associated with carbon-60 is approximately 4 angstroms. These results demonstrate the highest spatial resolution of light emission to date with a scanning probe technique.read more

Nano-optics of surface plasmon polaritons
TL;DR: A surface plasmon polariton (SPP) is an electromagnetic excitation existing on the surface of a good metal, whose electromagnetic field decays exponentially with distance from the surface.

Electron transport in molecular junctions.
TL;DR: An overview of some of the recent advances in electron transport through molecules attached to electrodes is presented and issues, including molecule–electrode contacts, local heating- and current-induced instabilities, stochastic fluctuations and the development of characterization tools are discussed.

Single molecules observed by near-field scanning optical microscopy.
Eric Betzig,Robert J. Chichester +1 more
TL;DR: Individual carbocyanine dye molecules in a sub-monolayer spread have been imaged with near-field scanning optical microscopy and the orientation of each molecular dipole can be determined to map the electric field distribution in the near- field aperture with molecular spatial resolution.

Single-molecule junctions beyond electronic transport
TL;DR: The emerging methods being used to interrogate multiple properties in single molecule-based devices are presented, how these measurements have advanced the understanding of the structure-function relationships in molecular junctions are detailed, and the potential for future research and applications are discussed.

Nanoscale science of single molecules using local probes
TL;DR: In revealing the crucial role of thermal, stochastic, and quantum-tunneling processes, experiments on individual molecules using scanning probe microscopies suggest that dynamics is inescapable and may play a decisive role in the evolution of nanotechnology.

Surface-enhanced Raman scattering
TL;DR: In this article, the authors developed a surface-enhanced Raman scattering (SERS) model of adsorbates on metal surfaces, where the long-range enhancement by resonances of the macroscopic laser and Stokes field is separated quantitatively from the metal electron-mediated resonance Raman effect.
