1. Annealing of Cu2ZnSn(S,Se)4 Thin Films : A Study of Secondary Compounds and Their Effects on Solar Cells
Sammanfattning : Kesterite Cu2ZnSnS4 (CZTS) is interesting as a sustainable photovoltaic technology due to its earth-abundant elements and suitable semiconducting properties. To date, a record efficiency of 12.6% has been achieved but further improvements are required to reach high efficiency for industrial implementation. LÄS MER
2. Annealing Based Optimization Methods for Signal Processing Applications
Sammanfattning : In this thesis, a class of combinatorial optimization methods rooted in statistical mechanics and their use in signal processing applications will be discussed. The thesis consists of two separate parts. LÄS MER
3. Characterisation and pickling behaviour of oxides formed during production annealing of stainless steel
Sammanfattning : .... LÄS MER
4. Fundamentals of substructure dynamics : In-situ experiments and numerical simulation
Sammanfattning : Substructure dynamics incorporate all features occurring on a subgrain-scale. The substructure governs the rheology of a rock, which in turn determines how it will respond to different processes during tectonic changes. LÄS MER
5. Variational Methods in Combinatorial Optimization and Phylogeny Reconstruction
Sammanfattning : Algorithms based on the variational approach, as used in statistical physics, are developed. For constraint satisfaction problems a novel cost function, based on information-theoretic arguments, is introduced, and an algorithm similar to the mean-field annealing algorithm is proposed. LÄS MER
