Abstract

The adsorption of xenon on hydrogen modified Pt(110)-(1 × 2) and on Pt(997) has been studied using TPD, LEED, XPS, and ARUPS. On Pt(110)-(1 × 2) with preadsorbed hydrogen, a single xenon species forming one-dimensional adsorbate chains in the [11̄0] direction is found. ARUPS shows well-resolved dispersion of the xenon 5p_1/2 and the split Sp_3/2 bands in the [11̄0] azimuth, but no dispersion in the [001] direction, in agreement with the packing density. On Pt(997) xenon decorates the close-packed steps in [11̄0] direction at low coverages. No dispersion of xenon bands is seen in ARUPS, indicating weak lateral adsorbate interaction along the chains as expected from the relatively large Xe-Xe distance of 5.6 Å extracted from LEED.
