Abstract
The Sn/Si(1 1 1)-(2√3×2√3)R30° surface has been reinvestigated with low temperature STM/STS and high resolution core level and valence band photoemission using synchrotron radiation. The experimental evidence indicates a 1.2 ML Sn coverage for this reconstruction, with 14 Sn adatoms per unit cell (only four of which are visible with STM). The surface is semiconducting with a band gap value of 0.8 ± 0.2 eV.
