Abstract

Two kinds of ordered reconstruction surface (√3 × √3) R30° and (√7 × √7) R19.1°, are prepared by depositing different amounts of Pt on Si(1 1 1). The atomic structure and electronic properties are studied by scanning tunneling microscopy and X-ray photoelectron spectroscopy. Then two models are built to explain the results. And the calculated results using density functional theory based first principle calculation show that the distance between Pt and Si atoms in (√7 × √7) R19.1° structure is smaller than that in (√3 × √3) R30° structure, which can increase the bonding energy between Pt and Si atoms.
