Structural Transformations of Zinc Oxide Layers on Pt(111)
... The STM images presented above show that the (4 × 4) structure is formed on areas initially uncovered by (6 × 6) islands. This implies the presence of small ZnOx clusters that migrate across the Pt(111) surface. Such species may also account for the tip instability and streaky STM images shown in Fi ...
