Rare gases physisorbed on Pt( [formula omitted]): a low-temperature STM investigation
The structure and the phase transitions of Xe, Kr and Ar physisorbed on Pt(1 1 1) in the submonolayer-coverage range has been explored by low-temperature scanning tunneling microscopy. The hexagonal incommensurate rotated (HIR) → hexagonal incommensurate (HI) transition with decreasing Xe coverage h...

The hexagonal incommensurate rotated (HIR) → hexagonal incommensurate (HI) transition with decreasing Xe coverage has been observed unambiguously.

The orientation of the high order of commensurability (HOC) Kr structure with respect to the surface strongly depends on the terrace width and on the step morphology. Kr monolayer misorientation ranging from 0° to 30° has been observed depending on the surface morphology.
The Ar monolayer adopts a HOC structure aligned with respect to the Pt(1
