Abstract
In the present work, several structural models compatible with the STM and XPD results were tested by tensor LEED analysis. The best agreement with the experimental I–V curves was obtained for a model similar to that proposed to interpret the STM images of the Ag(1 1 1)(4 4)–O phase. According to this structure, the protrusions observed in STM would correspond to tin atoms occupying on-top positions
