  3. 12. Low and High Energy Ion Beams in Nanotechnology

    Författare :Thomas Winzell; Kärnfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ion implantation; magnetic materials; ERDA; nanometer structures; Nuclear physics; MeV Ions; lithography; Kärnfysik; Fysicumarkivet A:2000:Winzell;

    Sammanfattning : In this thesis, two ways of fabrication of nanometer-sized semiconductor features are presented. Low Energy Ion Implantation (LEII) has been used to create shallow (sub-50 nm) and laterally small (5 m m – 200 nm) features by 10 keV As+ doping of B background doped Si. LÄS MER

  4. 13. Magnetic Thin Films with Graded and Tilted Anisotropy for Spintronic Devices

    Författare :Yeyu Fang; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : In this thesis magnetic thin films with graded or tilted anisotropy are intensively studied for potential applications in spintronic devices. A continuum of stable remanent resistance states is realized in Co/Pd multilayers based on a perpendicularly magnetized pseudo spin valve (PSV). LÄS MER

  5. 14. Growth and Magnetic Properties of Fe- and FeNi-based Thin Films and Multilayers

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

    Sammanfattning : 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. LÄS MER

  7. 15. Scanning probe microscopy studies of interaction forces between particles: emphasis on magnetite, bentonite and silica

    Författare :Illia Dobryden; Neil Thomson; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Experimentell fysik; Experimental Physics;

    Sammanfattning : Scanning probe microscopy (SPM), such as the atomic force microscope (AFM), using colloidal probes is a highly suitable technique to probe single particle-particle interactions in aqueous solution. The interaction force between a colloidal probe on the AFM cantilever and sample surface is measured. LÄS MER
