1. Electronic Structure and Transport Properties of Carbon Based Materials
Abstract : In the past decade the interest in molecular electronic devices has escalated. The synthesis of molecular crystals has improved, providing single crystals or thin films with mobility comparable with or even higher than amorphous silicon. Their mechanical flexibility admits new types of applications and usage of electronic devices. READ MORE

4. Semiclassical Analysis of Super-Shell Structure in Trapped Fermi Gases
Abstract : This dissertation investigates the oscillation part of the level density for trapped fermions. Analytical so-called trace formulae have been known for the two theoretically important potentials, the spherical cavity and harmonic oscillator, since more than thirty years. READ MORE

5. Chemical Bonding of Hydrocarbons to Metal Surfaces
Abstract : Using x-ray absorption spectroscopy (XAS), x-ray emission spectroscopy (XES) and x-ray photoelectron spectroscopy (XPS) in combination with density functional theory (DFT) the changes in electronic and geometric structure of hydrocarbons upon adsorption are determined. The chemical bonding is analyzed and the results provide new insights in the mechanisms responsible for dehydrogenation in heterogeneous catalysis. READ MORE
