16. Tailoring Properties of Materials at the Nanoscale
Abstract : The knowledge of growth and characterizing techniques is essential for the preparation of high quality thin films and multilayers. Here, structural properties have been investigated by X-ray reflectivity, X-ray diffraction, and transmission electron microscopy while the composition was determined by Rutherford backscattering spectrometry.

17. Industrial Alloys Studied by Surface Sensitive Techniques
Abstract : This thesis reports on surface studies of industrial materials whose importance for society manifests in the vast range of applications. In industrial materials alloying is performed in order to improve the parent material's physical and mechanical properties such as strength, corrosion and wear resistance, as well as high temperature performance in comparison to the pure metal.

18. Interaction of C60 with transition metals for thin film applications
Abstract : The fullerene molecule C60 is known to undergo many different chemical reactions, including intercalation of alkali- and alkaline earth metals. Relatively little is still known about the reaction between transition metals and C60, and the objective of this thesis was therefore-to investigate the chemical interaction between C60 and some group IV-VI transition metals.

19. Multilayer neutron optics based on isotope-enriched 11B4C
Abstract : The work in this thesis covers the design, growth and characterisation of neutron multilayers. The achieved reflectivity performance of a neutron multilayer depends on the achieved optical contrast between the layers as well as the achieved interface width between the layers. READ MORE

20. Single-crystal Mo/V superlattices : growth, structure, and hydrogen uptake
Abstract : 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. READ MORE
