Abstract
The reconstruction of the Pt(110) plane from an ordered (1 × 1) surface to an ordered (1 × 2) surface has been directly observed for the first time. The (1 × 1) surface, produced by field evaporation at 78 K, reconstructed at temperatures above 310 K. Field-ion images show clearly that the reconstructed surface consists of alternate missing rows of atoms. The transition was observed for clusters as small as five atoms, implying that the reconstructed surface is stabilized by shortranged, atomic interactions.Keywords
