6. Crystallographic Studies of Ternary Chalcogenides and Organic Semiconductors
Sammanfattning : X-ray diffraction methods have been used to study the crystal structure of different compounds, both organic and inorganic. The inorganic compounds were all synthesized by solid state reactions. A new compound, Re4As6S3, was synthesized and its structure was solved by Rietveld methods. LÄS MER
7. Magnetism of Semiconductors and Metallic Multilayers
Sammanfattning : Magnetic properties of diluted magnetic semiconductors and magnetic metallic multilayers are investigated by SQUID magnetometry. By doping GaAs with magnetic Mn2+ ions under well defined growth conditions, one obtains a diluted magnetic semiconductor, (Ga,Mn)As, in which the randomly-distributed magnetic ions act as acceptor centers.

8. Metal and Semiconductor Nanocrystals for Quantum Devices
Sammanfattning : Aerosol technology was used to develop new methods for fabrication of size-selected, nanometer-sized particles of metals and semiconductors. Such particles were used to realize different types of quantum devices and nanometer-sized structures. LÄS MER
9. Computational Material Design : Diluted Magnetic Semiconductors for Spintronics
Sammanfattning : The present thesis deals with the application of ab-initio electronic structure calculations based on density functional theory for material design.The correlation between magnetic properties and electronic structures has been investigated in detail for diluted magnetic semiconductors (DMS), which have promising application for spintronics devices.

10. Environmental Implications of Product Servicising. - The Case of Outsourced Computing Utilities
Sammanfattning : The life cycle of electronic products is associated with significant environmental impacts. Compared to many other products, the production of electronics and in particular semiconductors is resource intensive and generates a number of highly toxic waste streams in manufacturing and post-consumer stages of product life cycle.
