Abstract
Surface structures of Li/Cu (110) at 300 K were investigated by means of impact collision ion scattering spectroscopy (ICISS) and low-energy electron diffraction (LEED). A series of LEED patterns, (1×2), (1×1), (4×1), (5×1), and (n×1) where n < 8, were observed with an increase of Li coverage. The (1×2) structure is assigned to a missingrow-type restructuring of the Cu substrate atom induced by Li adsorption. The sequential structures of (4×1), (5×1) and so on were considered to belong to the same category, for which the structural model consists of Li atoms partially substituting for topmost Cu atoms and Li adatoms located in fourfold hollow sites on remaining Cu atoms.
