Scanning Tunneling Microscopy III Summary

Scanning Tunneling Microscopy III: Theory of STM and Related Scanning Probe Methods by Roland Wiesendanger

Scanning Tunneling Microscopy III provides a unique introduction to the theoretical foundations of scanning tunneling microscopy and related scanning probe methods. The different theoretical concepts developed in the past are outlined, and the implications of the theoretical results for the interpretation of experimental data are discussed in detail. Therefore, this book serves as a most useful guide for experimentalists as well as for theoreticians working in the field of local probe methods.
In this second edition the text has been updated and new methods are discussed.
