Abstract
Clean and oxygen-adsorbed platinum (113) surfaces were studied at room temperature by scanning tunneling microscopy (STM). It was found that a clean surface was reconstructed into a (1×2) missing row structure. Significant facetting was observed at the initial stage of annealing at 1150 K; however, wider (113) terraces were obtained after annealing for a longer time. After adsorption of atomic oxygen, the protruding atomic rows running in the [110] direction were separated by many dark nodes. The intervals of the nodes ranged from 6 to 9 Å, which corresponded to two or three times the atomic distance along the rows, suggesting that oxygen atoms were adsorbed at these intervals.
