摘要：

High-resolution core-level photoemission spectra of the K/Si(111)(7 x 7) surface system are presented. The Si 2p results show that potassium adsorption induces a Si 2p core level to shift to higher binding energy, i.e., to the opposite direction than that expected from the Si-K electronegativity differences. This result is compared with that of the K/Si(111)(unroofed radical 3BAR x unroofed radical 3BAR)R 30-degrees-B system and is interpreted in terms of the K-induced charge redistribution between the Si-adatom-rest-atom pair.
