摘要：

The electronic structure of the Si(111)-In(4X1) system, between the Fermi level and the vacuum level, has been studied using inverse photoemission. Single domain 4X1 overlayers were grown on vicinal Si(111) surfaces that were offcut by 3 degrees towards [<(11)over bar>2]. In contrast to an earlier inverse photoemission study of this system, which was performed on a multidomain sample, but in agreement with recent photoemission and STM studies, the overlayer system was found to be metallic. A clear Fermi level crossing was detected near the Brillouin zone boundary at (X) over bar. We suggest a possible reinterpretation of the inverse photoemission study that naturally resolves the controversy about the surface metallicity. [S0163-1829(97)00948-X].
