1. Electronic Structure of π-Conjugated Materials and Their Effect on Organic Photovoltaics
Sammanfattning : The great tunability of structure and electronic properties of π-conjugated organic molecules/polymers combined with other advantages such as light weight and flexibility etc., have made organic-based electronics the focus of an exciting still-growing field of physics and chemistry for more than half a century.

2. Doping and Density of States Engineering for Organic Thermoelectrics
Sammanfattning : Thermoelectric materials can turn temperature differences directly into electricity. To use this to harvest e.g. waste heat with an efficiency that approaches the Carnot efficiency requires a figure of merit ZT larger than 1. LÄS MER
3. Properties of multilayered and multicomponent nitride alloys from first principles
Sammanfattning : This thesis is a theoretical exploration of properties of multilayered and multicomponent nitride alloys, in particular their mixing thermodynamics and elastic behaviors. Systematic investigation of properties of a large class of materials, such as the multicomponent nitride solid solutions, is in line with the modern approach of high-throughput search of novel materials.

4. A domain-specific language for protocol stack implementation in embedded systems
Sammanfattning : Embedded network software has become increasingly interesting for both research and business as more and more networked embedded systems emerge. Well-known infrastructure protocol stacks are reimplemented on new embedded hardware and software architectures. LÄS MER
5. Excitonic and charge carrier transport in organic materials and device applications
Sammanfattning : With the potential for future commercial use, organic electronics have been intensively studied for the last few decades. To exploit the next generation of high-performance devices, detailed study of the underlying physics is essential. LÄS MER
