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

    University essay from

    Author : oussama ezzaher; [2023]
    Keywords : ;

    Abstract : 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. READ MORE

  3. 2. Bioactivity testing of dental materials

    University essay from Uppsala universitet/Tillämpad materialvetenskap

    Author : Alexander Eriksson; [2019]
    Keywords : Bioactivity; bioactive glass; soaking experiment;

    Abstract :  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. READ MORE

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

    University essay from Uppsala universitet/Materialfysik

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

    Abstract : 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. READ MORE

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

    University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

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

    Abstract : 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. READ MORE
