| مستخلص: |
Two interpretations have been proposed of dark triangles observed in scanning tunneling microscopy (STM) images of the best bound, [Square_Root]37×[Square_Root]37-R25.3°, and [Square_Root]39×[Square_Root]39-R16.1° periodic water monolayers on Pt(111). In one, a 'Y'-shaped tetramer of water molecules is removed, leaving a vacancy island behind; the other assumes the Y is replaced by a hexagon of H2O molecules, amounting to a di-interstitial. Consistent only with the di-interstitial model are thermal desorption and CO coadsorption data, STM line scans, and total energies obtained from density functional theory calculations.
