6. Boundaries of displacement : Belonging and Return among Forcibly Displaced Young Georgians from Abkhazia
Sammanfattning : This dissertation explores the implications of borders and boundaries for how forcibly displaced young Georgians from Abkhazia understand issues of belonging and return. My theoretical framework draws from theories on home and belonging as well as theories on border and boundary making, and locates them in geographies of uncertainty – or riskscapes – areas characterized by conflict and/or inequality.

7. Copper and Silver Metallization for High Temperature Applications
Sammanfattning : High-temperature electrical- and morphological-stability of interconnect is critical for electronic systems based on wide band gap (WBG) semiconductors. In this context, the thermal stability of both Ag and Cu films with Ta and TaN films as diffusion barriers and/or surface-capping layers at high temperatures up to 800 oC is investigated in this thesis.

8. Chromosome dynamics and genomic instablity in neuroblastoma. Three genomic pillars: MYCN amplification, numerical and structural changes
Sammanfattning : In this thesis, the main focus has been on the childhood cancer neuroblastoma, one of the most common and lethal childhood tumours. Neuroblastoma has througout the years continued to be a clinical and biological enigma. LÄS MER
9. Detailed photoemission studies of the prototype diluted magnetic semiconductor (Ga,Mn)As
Sammanfattning : Magnetic semiconductors are materials that combine the key features needed in information technology, namely magnetism and controllable charge transport. The prospects of integrating these properties and of using the spin as informa-tion carrier have motivated large efforts to produce such materials for imple-mentation in future spin-based electronics.

10. Nanowire Heterostructures- Growth, Characterization and Optical Physics
Sammanfattning : This thesis describes growth, processing, characterization and photoluminescence (PL) spectroscopy of nanowire heterostructures. The nanowires were made of III-V semiconductor materials and were produced by Au-particle assisted growth. LÄS MER
