Abstract
Li-adsorption on the Si(111)7 × 7 surface at room temperature has been studied for different metal coverages with core-level spectroscopy. Four Li-induced components are observed in the Si 2p level at high Li-coverages indicating the formation of four thermodynamically stable phases. It is shown that the reaction between the Li atoms and the Si(111)7 × 7 surface takes place in two steps. In the first the surface reconstructs towards a “7 × 1” reconstruction and in the second Li react with the Si-substrate, forming Li suicides, with the Si atom coordinating up to four Li neighbors.
