Popis: Scanning tunneling microscopy images of the Si(1 1 1)5×2–Au surfaces exhibit irregularly distributed protrusions of atomic size. They are identified as silicon adatoms by evaporating small amounts of silicon and gold onto the reconstructed surface. While extra silicon increases the density of protrusions, extra gold transforms the reconstruction partially into a Si(1 1 1)√3×√3 reconstruction.
