This book is a collection of selected papers presented at the First
Interna- ti onal Conference on the Structure of Surfaces (ICSOS-1).
ICSOS-1 was hel d on the Berkeley campus of the University of California
during August 13-16, 1984. The International Organizing Committee
members were: S.Y. Tong (Chairman), M.A. Van Hove (Vice-Chairman), D.A.
King (Secretary), D.J. Chadi (Treasurer), D.L. Adams, A.M. Bradshaw,
M.J. Cardillo, J.E. Demuth, J. Eckert, G. Ertl, B.I. Lundqvist, J.B.
Pendry, Y. Petroff, M. Simonetta, J.R. Smith, G.A. Somorjai, J. Stohr,
R. Ueda, and X.D. Xie. The series of ICSOS meetings was initiated to
assess the status of surface- structural determi nati on and the rel ati
onshi p between surface or interface structures and physical or chemical
properties of interest. The subject mat- ter includes solid and
adsorbate-covered surfaces, well-established and promising new
surface-sensitive techniques, and results of experimental and
theoretical studies. The physical and chemical properties of a surface
or interface are often critically determined by its atomic-scale
structure. A variety of techniques has been developed to study this
structure and its connection with the sur- face or interface properties
of single crystals and of imperfect and amor- phous interfaces. The
papers in this book cover the theory of surface structure, new analy-
tical techniques for surface structure, new developments in established
structural techni ques, recent structural resul ts, defect structures,
and phase transitions at surfaces.
