Sažetak
We present a study of sulfur adsorption on bare Ir(111). Two well-defined superstructures are found: a sqrt3R30 and a c(4 × 2) S- adlayer. Moreover, we also investigate sulfur intercalation of graphene on Ir(111). For adsorption, sulfur is provided either in the form of the precursor molecule H2S or as elemental sulfur through sublimation from FeS2 heated in a Knudsen cell. On the basis of scanning tunneling microscopy (STM) and low-energy electron diffraction (LEED), as well as density functional theory calculations (DFT), we present a model for the c(4 × 2) superstructure consistent with surface relaxations. We show that above a graphene coverage threshold, when islands of the two-dimensional (2D) material start to coalesce, the sulfur superstructure intercalated below graphene depends on the form in which sulfur is provided: c(4 × 2) forms in the case of exposure to elemental sulfur, while the sqrt3R30 superstructure forms in the case of H2S exposure. The two intercalation structures influence the graphene moiré corrugation in different ways. We have used DFT calculations to determine sulfur adsorption energies, surface relaxations, and the influence of sulfur intercalation on the density of electronic states of graphene on Ir(111).
