Atomic and electronic structure of surfaces and nanostructures

Analysis, control and modification of molecules, surfaces or nanostructures are great challenges of last years. We aim to study semiconductor surfaces and metal-semiconductor or organic-semiconductor interfaces on the atomic and the nanoscopic scale. Reconstruction, relaxation and dynamics on a monocrystalline surface after a deposition of metal atoms are monitored as a function of temperature and coverage. In our group we combine (i) nanoprobe technique (UHV VT STM/AFM), (ii) photoelectron spectroscopy (the source of synchrotron radiation "Elettra", Trieste, Italy) (iii) electron diffraction methods (LEED, SPA-LEED) and (iv) advanced theoretical analysis based on DFT simulations. The combination of these techniques allows state-of-art complex analysis of studied processes and systems.
