TLDR
Tunneling spectroscopy of Au(100) and Fe(5×20) surfaces has been studied in this paper, using a well-defined tunneling tip, I−S, I-V, and V/I*dI/dV-V spectra were obtained.Abstract:
Tunneling spectroscopy of Au(100)‐(5×20) and Fe on Au(100) surfaces has been studied. Using a well‐defined tunneling tip, I–S, I–V, and V/I*dI/dV–V spectra were obtained. The results confirm that the characteristics of the spectra resemble those of previously reported semiconductors. From I–S relations, it was found that the tunneling barrier decreases abruptly when the tunneling gap is <6 A.read more

Scanning tunnelling microscopy studies of metal surfaces
TL;DR: A survey of recent scanning tunnelling microscopy studies of single crystal metal surfaces under ultra-high vacuum conditions is presented in this paper, where the focus is on surface processes.

Self-surfactant effect on Fe/Au(100):: place exchange plus Au self-diffusion
TL;DR: In this article, the authors report on the submonolayer growth of Fe on Au(100), a system where a monolayer of the substrate floats at the external surface during growth facilitating the layer-by-layer growth of the Fe film.

Photon Emission from the Scanning Tunneling Microscope
TL;DR: In this paper, the concept of using the tip of a scanning tunneling microscopy (STM) as a source of low-energy electrons or holes to locally excite photon emission and thus study luminescence1 phenomena on nanometer-sized structures of metals, semiconductors and molecules is presented.

Transient tunneling current in laser-assisted scanning tunneling microscopy
TL;DR: The transient tunneling current induced by pulsed laser irradiation of a scanning tunneling microscope (STM) tunneling gap was observed to occur over a 100 μs time scale range in response to a 20 ns duration of the laser pulse as mentioned in this paper.

Molecular level studies of solid-gas and solid-liquid interfaces
TL;DR: The authors reviewed results from solid-gas interface studies as viewed from the perspective of relevance to solid-liquid interfaces, and correlated data obtained at the two interfaces wherever it is possible, and showed that the results obtained at these two interfaces represent systems of great and diverse technological importance.
