Scanning Tunneling Spectroscopy of Subsurface Ag and Ge Impurities in Copper
Thomas Kotzott, Mohammed Bouhassoune, Henning Prüser +3
We investigate single Ge and Ag impurities buried below a Cu(100) surface using low temperature scanning tunneling microscopy. The interference patterns in the local density of sta…
Substrate induced nanoscale resistance variation in epitaxial graphene
Anna Sinterhauf, Georg Alexander Traeger, Davood Momeni Pakdehi +8
Graphene, the first true two-dimensional material still reveals the most remarkable transport properties among the growing class of two-dimensional materials. Although many studies…
Fixing the Energy Scale in Scanning Tunneling Microscopy on Semiconductor Surfaces
Gerhard Münnich, Andrea Donarini, Martin Wenderoth +1
In scanning tunneling experiments on semiconductor surfaces, the energy scale within the tunneling junction is usually unknown due to tip-induced band bending. Here, we experimenta…
Mapping Itinerant Electrons around Kondo Impurities
Henning Prüser, Martin Wenderoth, Alexander Weismann +1
We investigate single Fe and Co atoms buried below a Cu(100) surface using low temperature scanning tunneling spectroscopy. By mapping the local density of states of the itinerant…
Theory of real space imaging of Fermi surfaces
Samir Lounis, Peter Zahn, Alexander Weismann +5
A scanning tunneling microscope can be used to visualize in real space Fermi surfaces with buried impurities far below substrates acting as local probes. A theory describing this f…
Band structure related wave function symmetry of amphoteric Si dopants in GaAs
S. Loth, M. Wenderoth, K. Teichmann +1
Autocompensated Si-doped GaAs is studied with cross-sectional scanning tunneling spectroscopy (X-STS). The local electronic contrasts of substitutional Si(Ga) donors and Si(As) acc…
