High-coverage oxygen structures on Rh(111): Adsorbate repulsion and site preference is not enough
(2004) In Physical Review Letters 93(26).- Abstract
- A new O induced structure on Rh(111) displaying a (2root3 x 2root3)R30degrees periodicity with an oxygen coverage of 2/3 has been studied by high resolution core level spectroscopy, scanning tunneling microscopy, and density functional theory. Although O favors fcc hollow sites in all other known phases, it occupies both fcc and hcp sites in this structure, which cannot be explained by pairwise adsorbate repulsion only. Both the (22root3 x 2root3)R30degrees and (2x2)-3O structures also exemplify that density-of-states contrast can lead to oxygen adatoms appearing as protrusions in scanning tunneling microscopy images.
