| Abstract | The dense Pb/Si(111)-alpha-root 3 x root 3 has been extensively studied over the last 20 years with scanning tunneling microscopy (STM) and surface diffraction to determine its structure and its phase transformations with temperature T and coverage theta. Two apparently incompatible models have been proposed for the structure and have been debated in the literature. One model was based on a coverage assignment theta=1 ML. The other model was based on assigning coverage in the range 1.2 ML |
