Dynamical Processes on Metal Surfaces-Scanning Tunneling Microscopy Studies.

Scanning tunneling microscopy applied to optical surfaces.

The technique of scanning tunneling microscopy has been applied to topographic mapping of two optical surfaces: a ruled grating replica and a diamond-turned gold mirror. We have demonstrated the ability of the scanning tunneling microscope to measure surface topography of a ruled-grating replica over an area of 2 microm x 2 microm. Furthermore, surface structure on a diamond-turned gold mirror ...

Scanning tunneling microscopy on rough surfaces-quantitative image analysis

In this communication, the application of scanning tunneling microscopy (STM) for a quantitative evaluation of roughnesses and mean island sizes of polycrystalline thin films is discussed. Provided strong conditions concerning the resolution are satisfied, the results are in good agreement with standard techniques as, for example, transmission electron microscopy. Owing to its high resolution, ...

Scanning tunneling microscopy studies of topological insulators.

Scanning tunneling microscopy (STM), with surface sensitivity, is an ideal tool to probe the intriguing properties of the surface state of topological insulators (TIs) and topological crystalline insulators (TCIs). We summarize the recent progress on those topological phases revealed by STM studies. STM observations have directly confirmed the existence of the topological surface states and cle...

Low-temperature Scanning Tunneling Microscopy and Spectroscopy of Noble-metal Surfaces*

Low-index surfaces of copper single crystals were studied by scanning tunneling microscopy (STM) and spectroscopy (STS). The experiments were performed under ultra-high vacuum conditions at roomand close to liquid heliumtemperatures. At lower temperatures thermal drifts are largely reduced, a better STM mechanical stability is achieved and improved spectroscopy measurements, with the energy res...
