    The effect of crystallography on the Hg 5d branching ratios (1990)

    Notes: The Hg 5d5/2 and 5d3/2 cross sections and branching ratios were measured in the photon energy range between 26 and 105 eV for Hg overlayers on Ag (100) and Cu (100). The branching ratios deviate from the nonrelativistic statistical value of 1.5, reaching values of 8.0. Data are presented that establish a direct relationship between the branching ratio and the long-range crystallographic structure of the Hg overlayers. This relationship is a consequence of the formation of a band structure from the shallow mercury 5d eigenstates.

    Core level photoemission of iodine overlayers (1988)

    Notes: We report the core level binding energies of chemisorbed iodine on Fe(110) and Fe(100). A decrease of 0.6 eV in the binding energies of the iodine core levels is observed with the increasing coverage of the chemisorbed iodine overlayer. This change in core level binding energies with coverage is compared with the results for iodine overlayers on other transition metal surfaces. The difference in core level binding energies between chemisorbed iodine on Fe(110) and molecularly adsorbed iodine on Fe(110) is explained using a Born–Haber cycle and an "equivalent'' cores approximation.

    The correlation between strain and electronic structure in monolayer thick films (1988)

    Notes: Abstract We explote and empirical relationship between strain (and lattice constant) and the valence electronic structure for mercury, bromine and iron overlayers. These overlayers have a range of lattice constants. For the Hg overlayers, all share a common cubic crystallography. We generally observe that the smaller the overlayer lattice constant, the greater the energy separation betweend-bands (Hg and Fe) orp-bands (Br). These results have important implications in relating electronic structure to fundamental properties such as magnetism. In addition, the film thickness limits for pseudomorphic growth calculated from the bulk properties are consistent with the experimental studies of Hg pseudomorphic growth on Ag (100) at 90 K.

    The influence of chemical environment upon the mercury 5d electronic structure (1990)

    Notes: We have investigated one and two monolayers of Hg adsorbed on Cu(100) by angle-resolved photoemission. The electronic structure of one monolayer of Hg on Cu(100) is very similar to that of the free atom. Two monolayers of Hg on Cu(100) has an electronic structure that closely resembles that of bulk Hg. These results are compared to those obtained for Hg overlayers on Ag(100). We have also observed that the shallow 5d core levels of the first monolayer of Hg shift by 0.38 ± 0.05 eV to greater binding energy following the adsorption of the second monolayer of Hg.
