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

The invention of the scanning tunneling microscope was a singularity event in the field of surface science and condensed matter physics. The ability to visualize individual atoms in an atomic structure was a huge step forward in experimental development, one for which the inventors were awarded the Nobel Prize in Physics in 1986. While a groundbreaking development, the Scanning Tunneling Micros...

Scanning tunneling microscopy

This paper begins with a brief introduction the development of scanning tunneling microscopy (STM); in the second part, we will present some basic theory about STM, we will pay more attention on the theory for tunneling between the surfaces of the sample with the model probe tip. Next, we introduce the STM facility, include different modes of operation and other influence factors. In addition, ...
