PREFACE
Phonons are always present in the solid state even at an
absolute temperature of 0 K where zero point vibrations still
abound. Moreover, phonons interact with all other excitations of
the solid state and, thereby, influence most of its properties.
Historically experimental information on phonon transport came
from measurements of thermal conductivity. Over the past two
decades much more, and much more detailed, information on phonon
transport and on many of the inherent phonon interaction processes
have come to light from experiments which use nonequilibrium
phonons to study their dynamics. The resultant research field has
most recently blossomed with the development of ever more
sophisticated experimental and theoretical methods which can be
applied to it. In fact, the field is moving so rapidly that new
members of the research community have difficulties in keeping up
to date.
This NATO Advanced Study Institute (ASI) was organized with
the objective of overcoming the information barrier between those
expert in the field and those who are new to it. Thus it was
decided to (i) organize a set of tutorially based lectures covering
most of the important facets in the field, and (ii) to produce an
Institute proceedings which would serve both as the first general
textbook, as well as a valuable reference book, for this field of
knowledge.
The set of lectures and this text are organized into two main
subjects. These are Nonequilibrium Phonon Dynamics in the Bulk,
and Phonons and Phonon Dynamics at (and near) Solid Surfaces. This
also represents, for the most part, the order in which the material
was presented during the ASI. Each lecturer presented essentially
all of his material during a single 3 1/4 hour period. Although
such a lecture period is quite an imposition on the lecturer, it
results in a more coherent form of presentation than when the
material is presented over fragmented periods of time. After each
three lecture periods, a full period of 3 1/4 hours was dedicated
to a general and completely open discussion period. The discussion
periods were under the leadership of a chairman and the three
v
PREFACE
previous lecturers. These periods were designed to offer to the
participants ample time to ask detailed questions on the previous
lectures (in a format useful to all the participants) and to make
comments and contributions of their own. All of the discussion
periods took up all their allotted time and would have taken more
if time had been available.
It became obvious as the ASI progressed that although much new
knowledge in the field of nonequilibrium phonon dynamics has come
to light in the past decade, much remains to be done before the
field can be considered to be fully mature. Perhaps the most
obvious missing links are theoretical formulations which are
readily reducible to comparison with experimental results. We
expect progress in this area in the future.
Some comments about the manuscripts. Modern word processors
have become an obvious tool for speeding up the typing of
camera-ready manuscripts. However, they lead to a wide spread of
typing fonts and in the general appearance of manuscripts, as
compared to the past when the IBM selectric typewriter, or its
equivalent, were the norm. I have, however, decided to accept this
spread in manuscript appearance so as not to undergo both the
expense and the consequent delay in retyping a number of the
manuscripts. Content is more important than form.
I also regretfully take note that the manuscripts by Professor
Bilz on the Dynamical Aspects of Nonlinear Oscillators and that by
Professor Maneval on the Thermal Response of Thin Metal Films were
not available at the time of publication.
The ASI was held in the Hotel du Golf, Les Arcs (Savoy),
France from August 27 through September 7, 1984 .. Situated some
1800 meters above sea level, and overlooking Mont Blanc and other
exceptionally beautiful scenery, the Hotel and its surroundings
became a welcomed relief from the ASI's full and, at times, hectic
program.
It goes almost without saying that an Institute of this scope
and size can not occur without the financial and organizational
help from a variety of sources. Most important, of course, was the
funding and organizational advice from the Scientific Affairs
Office of NATO. We are all grateful for their help. I would also
wish to thank the Max Planck Institut fuer Festkoerperforschung,
Stuttgart which helped to produce and mail the ASI's poster, and
the Physics Department at Indiana University who provided the
personnel for the second and subsequent mailings. The
U.S. National Science Foundation provided travel funding for three
young U.S. participants. The same is so for the science
foundations and universities of the countries of many of the other
lecturers and participants. We thank them all for their help and
PREFACE
trust that their aid to future ASIs will continue to assist
scientific communication.
I have also to thank many individuals whose aid helped to make
the ASI the success it turned out to be. Among these persons, I
would particularly like to acknowledge the help and advice of the
members of the Organizing Committee; namely, Professors L. Challis
and K. Renk, and of Professor J.-P. Maneval who undertook to be the
local coordinator and who made the original contact with the hotel
and, most importantly, battled with the vagaries of the
international banking system to balance the hotel phase of the
budget.
Many thanks go to Kathryn Crouch, my excellent secretary at
Indiana University. By far the greatest graditude goes to my wife,
Ann, who took on the secretarial and treasurers job during our
prolonged stay in Stuttgart during the summer of 1984, plus during
and after the ASI. Her help and organizational skills have been
acknowledged by lecturers and participants alike. Finally, my
thanks go to Mrs. J. Challis and Mrs. A.-M. Maneval who helped my
wife to staff the secretariat at Les Arcs, and to Mr. T. Gazaud and
Mr. P. Fabing of the staff of the Hotel du Golf for making our stay
there so pleasant.
