Die Heteroepitaxie von III-V auf Si und Ge Substraten eignet sich für kostengünstige, qualitativ hochwertige Epitaxieschichten, die eine geeignete Bandlücke für Mehrfachsolarzellen aufweisen. Jedoch ist die III-V-Heteroepitaxie auf diesen Substra

To gain a detailed insight into hydrogen embrittlement (HE) mechanisms in Fe, H diffusion in bulk Fe and its interaction with various defects using atomistic simulations were studied. These simulations were carried out with varying models of interato

A dynamic mean-field theory for spin ensembles (spinDMFT) at infinite temperatures on arbitrary lattices is established. The approach is introduced for an isotropic Heisenberg model with $S = \tfrac12$ and external field. For large coordination numbe

Density functional theory (DFT) is a powerful technique for studying various phenomena in materials science. In this thesis, several method developments are provided to capture the thermodynamics of defects in intermetallics using DFT. The importance

In this work, we reconstructed and full characterized a dislocation microstructure that formed during an in situ micro-cantilever beam experiment. Based on this information, we were then able to infer how the dislocations propagated from the notch in

In this thesis, the transport properties of the half-metallic Heusler alloy NiMnSb are investigated. For the electronic structure calculations, density functional theory, as implemented in SIESTA, was used. The transport calculations were performed w

Die Realstruktur des perowskitischen Modellsystems SrTiO3, welches in der Raumgruppe Pm-3m kristallisiert, wird durch die Sauerstoffvakanz als wichtigstem Defekt dominiert. Durch Temperaturbehandlung unter reduzierenden Bedingungen können Sauerstoff

In power electronic applications PowerMOSFET devices are used for the efficient conversion of energy. Since a vertical current flow through the silicon (Si) substrate exists, the substrates are heavily doped to minimize loss. But, during the growth o
