Abstract

The three-dimensional X-ray diffraction measurements, which directly mandate a single Au atom per unit cell, were utilized to determine the structure of Au/Si(557) surface. These measurements were made at beam line X16A of the National Synchrotron Light Source (NSLS). Heavy atom method in which the Au atom images the rest of the structure, was used for the analysis. It was found that Au atom was a substitute for a row of first-layer Si atoms in the middle of the terrace, which then reconstructed by step rebonding and adatoms.
