Angle Resolved Photoemission Study and Calculation of the Electronic Structure of the Pt(111) Surface
Russian Foundation for Basic Research
Angle resolved photoemission spectra of Pt(111) were measured along the ΓK and ΓM direction of the surface Brillouin zone (SBZ). The electronic structure of a semi-infinite Pt(111) crystal was calculated applying the LMTO-TB approximation to aid interpretation of the spectra. The experimental spectra are well described by the calculated bulk band structure. Both the experiment and calculation reveal a surface state near the Fermi level in the neighborhood of the K point of the SBZ.
