    • Changes in the electronic structure of Yb, a material whose valence is modified under pressure, are observed with remarkable detail in x-ray absorption and emission data measured between ambient conditions and 20 GPa. These changes are reproduced by a theory that essentially does not rely on experimental parameters, and includes dynamical core-hole screening. From the combined experimental and theoretical data we can firmly establish on a quantitative level how the valency of an intermediate valence material is modified by pressure. In metallic Yb it increases from 2 to 2.55 +/- 0.05 between 0 and 20 GPa.

    • In a series of experiments in externally electrically heated diamond anvil cells we demonstrate that at pressures above similar to 240 GPa gold adopts a hexagonal-close-packed structure. Ab initio calculations predict that at pressures about 250 GPa different stacking sequences of close-packed atomic layers in gold become virtually degenerate in energy, strongly supporting the experimental observations.

  • Entrepreneurship, social capital and governance : Directions for the sustainable development and competitiveness of regions
  • 2012. - 1
  • Samlingsverk (redaktörskap) (refereegranskat)abstract
    • This book highlights the role of entrepreneurship, social capital and governance for regional economic development. In recent decades, many researchers have claimed that entrepreneurship is the most critical factor in sustaining regional economic growth. However, most entrepreneurship research is undertaken without considering the fundamental importance of the regional context. Other research has emphasized the role of social capital but there are substantial problems in empirically relating measures of social capital to regional economic development. © Charlie Karlsson, Börje Johansson and Roger R.

  • Point defects on the (110) surfaces of InP, InAs, and InSb : A comparison with bulk
  • 2006
  • Ingår i: Physical Review B. Condensed Matter and Materials Physics. - 1098-0121 .- 1550-235X. ; 74:7
  • Tidskriftsartikel (refereegranskat)abstract
    • The basic properties of point defects, such as local geometries, positions of charge-transfer levels, and formation energies, have been calculated using density-functional theory, both in the bulk and on the (110) surface of InP, InAs, and InSb. Based on these results we discuss the electronic properties of bulk and surface defects, defect segregation, and compensation. In comparing the relative stability of the surface and bulk defects, it is found that the native defects generally have higher formation energies in the bulk. From this it can be concluded that at equilibrium there is a considerably larger fraction of defects at the surface and under nonequilibrium conditions defects are expected to segregate to the surface, given sufficient time. In most cases the charge state of a defect changes upon segregation, altering the charge-carrier concentrations. The photothresholds are also calculated for the three semiconductors and are found to be in good agreement with experimental data.
