  1. 1. Crystallinity of Sputtered TiO2 Thin Films: a Study of the Heating and Plasma Influence on the Growth

    Master-uppsats,

    Författare :oussama ezzaher; [2023]
    Nyckelord :;

    Sammanfattning : AbstractHigh-Power Impulse Magnetron Sputtering (HIPIMS) of TiO2 thin films enhances their photocatalyticproperties compared to the films prepared by standard sputtering methods, especially when no substrateheating is employed. With no heating, the coatings present an amorphous structure that benefits from theionization of the sputtered flux granted by HiPIMS, with respect to their photocatalytic performance. LÄS MER

  3. 2. Bioactivity testing of dental materials

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad materialvetenskap

    Författare :Alexander Eriksson; [2019]
    Nyckelord :Bioactivity; bioactive glass; soaking experiment;

    Sammanfattning :  Ever since Hench et al. first discovered bioactive glass in 1969, extensive interest was created because of the materials ability to chemically bond with living tissue. In this project the bioactivity of three different compositions of the bioactive glass Na2O-CaO-SiO2 have been studied. LÄS MER

  4. 3. Finite-size effect in CoAlZr/AlZr multilayers

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Materialfysik

    Författare :Fredrik Backer-Meurke; [2018]
    Nyckelord :Magnetism; thin film; Co; AlZr; Magnetic materials;

    Sammanfattning : The structural and magnetic properties of amorphous Cox(Al80Zr20)1-x multilayers with varying thicknesses of the magnetic bilayers have been investigated. The reduction of the thickness causes a reduction of the critical temperature, Tc, this is known as the finite-size effect. LÄS MER

  5. 4. Ferroelectricity in nanocrystalline Hf0.5Zr0.5O2 thin films

    Master-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Författare :Lun Sang; [2018]
    Nyckelord :ferroelectricity; Hf0.5Zr0.5O2; GIXRD; XRR; Technology and Engineering; Physics and Astronomy;

    Sammanfattning : Hafnium dioxide (HfO_2) based thin films doped with various dopants (Si, Ge, Al, Gd, Sr, Zr) have been found to exhibit ferroelectricity. These dopants were found to stabilize the III orthorhombic phase in the hafnium oxide based thin films. LÄS MER
