Tin (Sn) adsorption on Si(1 0 0) surface has been studied by scanning tunneling microscopy (STM) and co-axial impact collision ion scattering spectroscopy (CAICISS). The c (8 × 4) and (5 × 1) phases were analyzed to reveal their atomic structure. It has been confirmed that the c (8 × 4) structure consists of buckled Sn dimers. The (5 × 1) structure has been found to be partially irregular along (5 × 1) rows and to consist of double Sn layer. The Sn atoms in the first layer are undimerised while those in second layer form asymmetric dimers.
