1. Photosynthetic Oxygen Evolution - EPR studies of the manganese cluster of photosystem II
Abstract : In this thesis, a new electron paramagnetic resonance (EPR) signal from photosystem II is presented. The signal is shown to originate from the S0 oxidation state of the oxygen-evolving complex (OEC). READ MORE

2. Cadmium Free Buffer Layers and the Influence of their Material Properties on the Performance of Cu(In,Ga)Se2 Solar Cells
Abstract : CdS is conventionally used as a buffer layer in Cu(In,Ga)Se2, CIGS, solar cells. The aim of this thesis is to substitute CdS with cadmium-free, more transparent and environmentally benign alternative buffer layers and to analyze how the material properties of alternative layers affect the solar cell performance.

3. Methods for Stochastic Optimal Control under State Constraints
Abstract : This thesis looks at a few different approaches to solving stochas-tic optimal control problems with state constraints. The motivatingproblem is optimal control of an energy buffer in a hybrid vehicle,although applications are abundant in a number of areas. READ MORE

4. Design, Fabrication and Characterization of GaN HEMTs for Power Switching Applications
Abstract : The unique properties of the III-nitride heterostructure, consisting of gallium nitride (GaN), aluminium nitride (AlN) and their ternary compounds (e.g. AlGaN, InAlN), allow for the fabrication of high electron mobility transistors (HEMTs). READ MORE

5. Energy and Design Cost Efficiency for Streaming Applications on Systems-on-Chip
Abstract : With the increasing capacity of today's integrated circuits, a number ofheterogeneous system-on-chip (SoC) architectures in embedded systemshave been proposed. In order to achieve energy and design cost efficientstreaming applications on these systems, new design space explorationframeworks and performance analysis approaches are required. READ MORE
