Abstract : The electronic structure of segregated c(2x2)S/Fe(100) was determined using synchrotron radiation and angle-resolved photoemission. In addition to mapping the S 3p-derived energy bands, the lineshapes of the S photoemission features were correlated to their surface Brillouin zone position. The dispersions of the bands derived from in-planes S 3 Psub-X Psub y levels are induced by S-S interactions, and are well described by a tight-binding model. The S 3pz-derived band is anomalously wide (1.2eV) compared to the tight-binding width, which is a substrate-induced effect.
