Abstract: 

A combined investigation using thermal desorption spectroscopy (TDS) and low-energy electron diffraction (LEED) shows that the area of the Li-induced 3×1 reconstruction on Si(111) depends linearly on the amount of adsorbed Li. This is in contrast to the concept of an impurity-stabilized 3×1 reconstruction by a small amount of Li through a long-ranged mechanism. The desorption energy of the Li atoms involved in the reconstruction is 3.2 eV. This is substantially higher than that of Li desorbing from the Si(111)7×7 surface (2.5 eV). The high desorption energy points to saturation of dangling bonds by Li chemisorption, which also explains the passivation of the Si(111)3×1–Li surface against oxidation.
