Low-Dimensional Systems:

Nanostructures on Surfaces

(E. Bertel, N. Memmel, A. Menzel)


Preparation of low-dimensional nanostructures, such as supported nanowire and quantum dot arrays, via self-assembly. Characterisation of the geometry and the phase diagram by means of variable-temperature scanning tunnelling microscopy (VT-STM), low-energy electron diffraction (LEED) including dynamical LEED measurements for exact structure determination (IV-LEED) and spot-profile analysis (SPA-LEED). Determination of the electronic structure and electron correlation effects by angle-resolved UV photoemission spectroscopy (ARUPS).
Characterisation of electronic surface properties of ultra-nanocrystalline diamond in comparison with single-crystal diamond by means of x-ray photoelectron spectroscopy (XPS) and UV photoelectron spectroscopy (UPS). Tailoring of surface properties by means of different surface terminations and surface doping.
