Abstract
The room-temperature interaction of Co overlayers with the cleaved InP(110) surface has been studied using soft-x-ray core-level photoemission spectroscopy. We show that Co strongly reacts with the surface to form phosphide. For small metal coverages the reacted overlayer grows in a laminar fashion. The pinning position for the 1.5-Å Co coverage is approximately 0.30 eV below the conduction-band minimum. For higher coverages the pinning is difficult to follow due to the uncertainty in accounting for the chemical reactions in the core-level spectra.Keywords
