Lectures on Surface Science

The Fourth Latin-American Symposium on Surface Physics (SLAFS 4) was held from July 14 to 18, 1986, at the Unversidad Central de Venezuela, Caracas, Venezuela, as part of a program of the Centro Latinoamericano de Fisica (CLAF) aimed at improving the scientific relations and coop eration among Latin-American researchers in the field of surface physics. This symposium, which brought together about 60 scientists, included 12 invited talks given by internationally recognized experts covering a wide range of surface physics topics and showing the most recent develop ments of the theory and spectroscopies involved. This proceedings volume contains the text of the 12 invited lectures plus a selection of the Latin American contributed papers. The topics covered during the conference were: thin films, chemisorption theory, and surface spectroscopies such as high resolution electron energy loss spectroscopy (HREELS), inverse pho toemission, Auger deexcitation, SEXAFS, LEED, Raman spectroscopy (SERS) and deuteron solid state FT-nuclear magnetic resonance spec troscopy. There were also some contributions related to the application of surface analysis to the chemical and semiconductor industries. In addi tion to the talks there were two poster exhibitions, which showed mainly Latin-American contributions, making it possible to discuss extensively the work presented. Finally, we wish to acknowledge the assistance given by the local or ganizing committee, especially the diligent cooperation of Luis Cortina, Ivan Escalona, Helena Isern, Miguel Martin, Claudio Mendoza and Ivar Pettersson in developing the symposium program.
