TLDR

By placing a photon detector near the tip-sample region of a scanning tunneling microscope, we have measured isochromat photon-emission spectra of polycrystalline tantalum and Si(111)7×7 at photon energies of 9.5 eV. Such spectra contain electronic-structure information comparable to inverse photoemission spectroscopy, but with high lateral/spatial resolution. The implications of this new observation are discussed.read more

Antennas for light

TL;DR: Optical antennas are devices that convert freely propagating optical radiation into localized energy, and vice versa as mentioned in this paper, and hold promise for enhancing the performance and efficiency of photodetection, light emission and sensing.

TL;DR: 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.

Electrical excitation of surface plasmons.
TL;DR: This work shows that electron tunneling provides a nonoptical, voltage-controlled, and low-energy pathway for launching SPPs in nanostructures, such as plasmonic waveguides.

Photoassisted scanning tunneling microscopy
TL;DR: A review of light-induced effects in tunneling microscopy can be found in this article, where the authors discuss thermal effects, nonlinear effects, field enhancement at the STM tip, various effects on semiconductor surfaces, excitation of surface plasmons, detection of photoelectrons, spin-polarized tunneling, local optical spectroscopy, the use of ultrashort laser pulses for time-resolved STM, and the combination of STM and scanning near-field optical microscopy.
Journal ArticleDOI
Photon emission experiments with the scanning tunnelling microscope
TL;DR: In this paper, the authors detected the light emitted from an STM at both ultraviolet (9·5 eV) and optical (1−4 eV), and showed that this light contains spectroscopic information on the sample surface comparable to conventional inverse photoelectric spectroscopy, but with nearly atomic spatial resolution.

Vacuum tunneling current from an adsorbed atom.
TL;DR: In this article, the tunneling current density is computed in the vacuum region between two planar metal electrodes, on one of which is an adsorbed atom, using self-consistent wave functions for each electrode; the effects of adatom valence resonances are fully taken into account.
