1. Electronic Transport in Strained Materials
Abstract : In this thesis the conductivity of strained materials has been investigated using density functional theory and a semiclassical transport theory based on the Boltzmann equation.In transition metals trends are reproduced without adjustable parameters. READ MORE

2. Electronic Properties of Diamond
Abstract : Diamond is a semiconductor with many superior material properties such as high breakdown field, high saturation velocity, high carrier mobilities and the highest thermal conductivity of all materials. These extreme properties compared to other (wide bandgap) semiconductors make it desirable to develop single-crystalline epitaxial diamond films for many electronic device and detector applications.

3. Upscaling Organic Electronic Devices
Abstract : Conventional electronics based on silicon, germanium, or compounds of gallium require prohibitively expensive investments. A state-of-the-art microprocessor fabrication facility can cost up to $15 billion while using environmentally hazardous processes. READ MORE

4. Electronic Transport in Materials
Abstract : Transport properties within the Boltzmann transport equation for metallic multi-layer structures as well as bulk materials, were the prime topic of this work. Ab initio total energy calculations for Hydrogen loaded metallic multi-layers were performed in order to shed some light onto problem of H depleted layers at the interfaces that have been experimentally observed.

5. Characterization of Conduction and Polarization Properties of HVDC Cable XLPE Insulation Materials
Abstract : High voltage direct current (HVDC) cables with extruded insulation system were introduced in 1998. Since then this technology has been growing rapidly with many installations that are today operational at voltages up to 320 kV. READ MORE
