1. A Theoretical Study of Atomic Trimers in the Critical Stability Region
Abstract : When studying the structure formation and fragmentation of complex atomic and nuclear systems it is preferable to start with simple systems where all details can be explored. Some of the knowledge gained from studies of atomic dimers can be generalised to more complex systems. READ MORE

2. Electronic and atomic structure of metal induced reconstructionson Si(lll) and Ge(lll) surfaces studied by PES and STM
Abstract : Deposition of metal atoms on semiconductors leads in many cases to reconstructed surfaces. The lack of symmetry in the direction normal to the surface allows for a large variety in the atomic arrangements of the surface reconstructions. In the case of silicon, more than 300 kinds of adsorbate-induced surface reconstructions have been found. READ MORE

3. Density Functional Theory Studies of Small Supported Gold Clusters and Related Questions : What a Difference an Atom Makes
Abstract : During the last decades the specific manipulation of matter on the (sub-) nanometer scale, also known as nanoscience, became possible by technologies such as the scanning tunneling microscope. Nanocatalysts, i.e. catalytic active structures of up to a few nanometers in size, belong to this rather new class of materials. READ MORE

4. A theoretical study of mass transport processes on TiN(001) and mechanical properties of TiN- and VN-based ternaries
Abstract : This thesis concerns computer simulations, using classical molecular dynamics, of transport processes related to TiN(001) growth. It is motivated from the challenge to understand transport processes at the atomic scale responsible for crystal and film growth and their different growth modes. READ MORE

5. Experimental and Theoretical Studies of Metal Adsorbates Interacting with Elemental Semiconductor Surfaces
Abstract : Metal adsorbates on semiconductor surfaces have been widely studied over the last few decades. The main interest is focused on various one or two-dimensional structures that exhibit interesting electronic and atomic properties. This thesis focuses on metal adsorbates interacting with the Si(111) and Ge(111) surfaces. READ MORE
