The work is aimed at characterizing structural defects on crystal               surfaces and investigating their role in atom transport                         processes.  The mechanisms by which atoms move on surfaces to                   produce morphology changes and surface phase transitions will be                studied.  A major part of the work will involve the study of                    atomic steps on single crystal surfaces; it will be concerned                   with atomic structure in the vicinity of steps, kink                            distributions along individual steps, interactions of pairs and                 groups of steps, the dynamics of step motion during mass                        transport processes and the correlation of nucleation sites for                 phase transitions with step edges.  The major experimental                      methods for the structural and kinetic studies will be scanning                 tunneling microscopy, low energy electron diffraction, and                      surface x-ray diffraction.  Experiments will be performed both on               semiconductors and on metal single crystals.
