  2. 21. A Structural Viewpoint of Magnetism in Fe and Co Based Superlattices

    Author : Matts Björck; Gabriella Andersson; Adrian Rennie; Thomas Hase; Uppsala universitet; []
    Keywords : Physics; Magnetism; Multilayer; Superlattice; X-ray magnetic circular dichroism; X-ray diffraction; X-ray reflectivity; Neutron diffraction; Structural refinement; Interfaces; Fysik;

    Abstract : In order to understand the properties of thin film devices, knowledge of the material's structure is essential. The work presented here combines magnetic and structural characterization of the systems studied to gain a deeper physical understanding. READ MORE

  4. 22. Growth and Magnetic Properties of Fe- and FeNi-based Thin Films and Multilayers

    Author : Anna Maria Blixt; Björgvin Hjörvarsson; Gabriella Andersson; Panagiotis Poulopoulos; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Sputter growth; Permalloy; Multilayer; Superlattice; Magnetism; Fysik; Physics; Fysik;

    Abstract : This thesis concerns the growth and magnetic properties of thin films and multilayers. The samples were grown by magnetron sputtering, and characterized structurally mainly by x-ray diffraction and reflectivity. READ MORE

  5. 23. Bacteria-responsive materials for drug delivery

    Author : Marina Craig; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; triggered release; multilayer; controlled release; Layer-by-layer; nanofilm; infection; enzymatic degradation;

    Abstract : The number of diabetics, obese individuals and other patients carrying other lifestyle diseasesis increasing worldwide. At the same time the population is ageing. These patients all sufferfrom poor blood circulation, which often gives rise to non-healing, or chronic, wounds. Thus,the number of chronic wounds is also increasing at a fast pace. READ MORE

  6. 24. Electronic Transport in Strained Materials

    Author : Thomas Dziekan; Susanne Mirbt; Olle Eriksson; Per Hyldgaard; Uppsala universitet; []
    Keywords : Physics; Conductivity; Strain; Transport; Boltzmann theory; Transition metal; Hydrogen loading; Electronic structure; Density functional theory; Bulk material; Multilayer; Fysik;

    Abstract : In this thesis the conductivity of strained materials has been investigated using density functional theory and a semiclassical transport theory based on the Boltzmann equation.In transition metals trends are reproduced without adjustable parameters. READ MORE

  7. 25. Optical Studies of Periodic Microstructures in Polar Materials

    Author : Herman Högström; Carl Gustaf Ribbing; Clivia M. Sotomayor Torres; Uppsala universitet; []
    Keywords : Engineering physics; polaritonic; polar; photonic crystal; surface phonon polariton; multilayer; Reststrahlen; SiC; SiO2; Teknisk fysik;

    Abstract : The optical properties of matter are determined by the coupling of the incident electromagnetic radiation to oscillators within the material. The oscillators can be electrons, ions or molecules. Close to a resonance the dielectric function exhibits strong dispersion and may be negative. READ MORE
