1. Carbide and MAX-Phase Engineering by Thin Film Synthesis
Sammanfattning : This thesis reports on the development of low-temperature processes for transition metal carbide and MAX-phase thin film growth. Magnetron sputtering and evaporation, far from thermodynamical equilibrium, have been utilised to engineer the properties of the films by physical and chemical control. LÄS MER
2. Theoretical and computational advances in small-angle x-ray scattering tensor tomography
Sammanfattning : The relationships between microscopic and macroscopic structures is a central topic of materials physics. Small-angle x-ray scattering (SAXS) is a powerful experimental technique for probing and mapping variations in electron density, given by the reciprocal space map, down to the nanometer scale in two dimensions.

3. Near-infrared photodetectors based on Si/SiGe nanostructures
Sammanfattning : Two types of photodetectors containing Ge/Si quantum dots have been fabricated based on materials grown by molecular beam epitaxy and characterized with several experimental techniques. The aim was to study new device architectures with the implementation of Ge nanostructures, in order to obtain high detection efficiency in the near infrared range at room temperature. LÄS MER
4. An Electron Microscopy Study on Materials in Electronic Packaging
Sammanfattning : This thesis is concerned with an investigation of the microstructure on materials in electronic packaging. The materials include Ag-filled conductive adhesives, Sn-Ag-based lead free solders and metal-oxide semiconductors. LÄS MER
5. Single-crystal Mo/V superlattices : growth, structure, and hydrogen uptake
Sammanfattning : Fundamental studies concerning the growth, structural characterization and hydrogen uptake of single-crystal (00 l )-oriented Mo/V superlattices have been performed. The superlattices were grown by dual-target magnetron sputtering in pure Ar-atmosphere < 6·10-3 Torr on (001)-oriented MgO substrates. LÄS MER
