Abstract

The structural and electronic properties of a Pt(111)-Ge surface alloy are studied by scanning tunneling microscope and angle-resolved photoemission spectroscopy. The electronic band structure in the Γ-L direction was measured and compared with that of Pt(111). The crystal field parameters of 10Dq and ξ were evaluated to be 1.77 eV and 0.73 eV respectively. Alloying with Ge was found to reduce 10Dq and enhance ξ compared with pure Pt(111).
