摘要：
A photoemision study of the surface states on Be(10 (1) over bar0) after Li adsorption at room temperature is reported. The surface band structure was mapped along four high symmetry directions of the SBZ. Fairly large shifts in the surface band locations were obtained but all surface states observed experimentally after Li adsorption were found to correspond to Be-derived states and no Li-derived surface states could be identified. The surface state bands located close to the Fermi level (E-F) were found to be affected the most and it is suggested that one surface state band which on the clean surface is located above E-F is pulled down below E-F after Li adsorption.
