The morphology of the Au(111) surface exposed to oxygen under high pressure (p O2 = 1 bar) and high temperature (500 ≤ T ≤ 800°C) during a prolonged period of time (between 1/2 and 24 h) was investigated by scanning tunneling microscopy (STM). At the atomic scale the surface exhibits a (√3 √3)R30° structure which is ascribed to atomic oxygen being strongly chemisorbed at the gold surface...
We report a scanning tunnelling microscopy (STM) study of the surface morphology of Au(111) exposed to oxygen at high temperature (700-800°C) and high pressure (1 bar). Two types of oxygen induced surface structures were observed: (i) a hexagonal long-range reconstruction with a periodicity of ∼ 65 and a corrugation of about 0.5 . At the atomic scale this surface exhibits a (√3 √3)R30° structure,...
