Description
Description
Surface Alloys and Alloy Surfaces is concerned with the structural, compositional, electronic and chemical properties of the
surfaces of solids in which the surface layers, at least are alloyed. Two different categories of system are covered - the surfaces of
bulk alloys (alloy surfaces) and surface phases in which one or more outermost atomic layers are alloyed, while the underlying bulk involves
no such intermixing (surface alloys).
Importance of Topic
The surfaces of bulk alloys have long been known to be of practical interest
for their chemical properties. It has also long been known that the surface composition of such alloys commonly differs from that of
the underlying bulk. However, our understanding of these chemical and physical phenomena is far from complete and the application of
surface science methods to investigate these phenomena is a manifestation of a general trend to study the surfaces of increasing complexity.
Surface alloy formation, as a much more recently recognized phenomenon deserves more attention.
Why This Title
This title is important
as it provides new insights into a mixture of new and old problems. It is the first to cover the important mixture of material on surface
alloys and alloy surfaces. Each chapter is written by experts in different areas of these two interrelated topics, covering theory and
experiment, physics and chemistry, geometrical and electronic structure. The coverage of the surface alloy topic is especially novel
as it is relatively newly-recognised as quite a common phenomenon.
Audience
For research institutes concerned with surface science, condensed matter physics, physical chemistry and catalytic chemistry. For university
departments and libraries concerned with physics, chemistry, chemical engineering and materials science.
