Combined investigation of STM, high-resolution synchrotron photoemission, and density functional theory calculations allowed us to understand the Sb-induced structural-transformation of Si(114)-2×1. When 2ML of Sb is deposited on Si(114)-2×1 at room temperature and postannealed at 500°C, all of the surface Si atoms with dangling bonds are replaced by Sb atoms. Among one-dimensional (1D) structures...
