Beschreibung:
  • Epitaxial Fe(110) films grown on W(110) substrates exhibit, up to the second pseudomorphic monolayer, a peak in (Formula presented) spectra at 0.2 eV above the Fermi level as measured by scanning tunneling spectroscopy (STS). It is shown directly by STS on nanometer-scale wedges of Fe/W(110) that the density of empty states is diminished wherever the stressed Fe film begins to relax. The change in local differential conductivity can therefore be explained by a stress-induced change of electronic structure for the first two monolayers due to the large misfit between film and substrate. © 1996 The American Physical Society.
