摘要：

We describe a method for the in situ study of step decoration modes in vapor-phase epitaxial growth. It is based on the large cross-section of thermal energy He atoms for diffuse scattering exhibited by surface defects. In grazing-incidence scattering geometry, this sensitivity can be used to monitor ordering and growth processes at step edges. We illustrate the method with results for Ag and Pt deposition at the (111) steps on the vicinal Pt(997) surface. (C) 1998 Elsevier Science B.V. Al rights reserved.
