The presence of InAs quantum dots on a {100} GaAs surface results in a pronounced increase of the Fermi level pinning energy. Using room-temperature photo-reflectance measurements combined with atomic force microscopy, we find that the presence of th

The CO/CO 2 conversion performed over a Ru(0001) surface shows the decisive role of subsurface oxygen which explains the discrepancy between former UHV results and high pressure experiments. At oxygen pressure higher than about 10 -3 mbar the oxygen

After deposition of submonolayer quantities of iridium on Cu(100) at 200 K strong intermixing of both species has been found by means of low energy ion scattering (ISS) and scanning lunneling microscopy (STM) measurements. The incorporated Ir atoms a

In magnetically polarized ultrathin Pd films with (111) orientation, grown on a Ni(001) single crystal, static magnetic hyperfine fields were measured at the interface using perturbed angular correlation spectroscopy. The structural arrangement of th

The epitaxial growth and the structure of Cu on Si(111)7×7 was investigated by scanning tunneling microscopy (STM) and Auger electron spectroscopy. The so-called quasi-“5×5” incommensurate structure of Cu/Si(111) was observed by STM with atomic
