Scanning Tunneling Microscopy II, like its predecessor,
presents detailed and comprehensive accounts of the basic
principles and broad range of applications of STM and
related scanning probe techniques. The applications
discussed in this volume come predominantly from the fields
of electrochemistry and biology. In contrast to those
described in Vol. I, these sudies may be performed in air
and in liquids. The extensions of the basic technique to
map other interactions are described inchapters on scanning
force microscopy, magnetic force microscopy, scanning
near-field optical microscopy, together with a survey of
other related techniques. Also described here is the use of
a scanning proximal probe for surface modification.
Togehter, the two volumes give a comprehensive account of
experimental aspcets of STM. They provide essentialreading
and reference material for all students and researchers
involvedin this field.
