The objective of the investigation is to systematically study the               structure of surfaces of semiconductor materials.  The program                  will emphasize impact collision ion scattering spectroscopy,                    scanning tunneling microscopy, and first principles                             pseudopotential total energy theoretical calculations.  Impact                  collision ion scattering spectroscopy identifies the atomic                     species on the surface and provides structural information on the               crystallographic unit cell of the surface atoms.  The scanning                  tunneling microscopy provides an image of the surface on a                      localized atomic scale in three-dimensional scale.  Total energy                calculations give detailed information pertaining to the                        equilibrium atomic and electronic structures.                                                                                                                   The research is relevant to the surface of semiconducting                       materials used in integrated electronics, especially to the                     important topic of metallization.
