THE STRUCTURE AND DYNAMICS OF CRYSTAL-SURFACES AT HIGH-TEMPERATURES

After a brief review of the historical evolution of the understanding of crystal surfaces at high temperatures in general the subject is narrowed down to fcc metal surfaces, in particular to (110) surfaces. The recent work on these surfaces is reviewed, with emphasis on Pb, and the interpretation of the results in terms of various kinds of disordering such as surface melting, surface roughening, anharmonic vibrations and other processes is critically examined. While some of the results are now well established, others are contradictory, so that no unambiguous picture of metal surfaces at high temperatures can be given at present. © 1990 Springer-Verlag.
