  1. 6. 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

  3. 7. 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

  4. 8. Structural Investigations of HiPIMS-deposited Diamond-Like Carbon Thin Films using Raman Spectroscopy

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Fasta tillståndets elektronik

    Författare :Andreas Eriksen Tell; [2017]
    Nyckelord :;

    Sammanfattning : Diamond-like carbon (DLC) is a versatile material which exhibits excellentmechanical, electrical and optical properties making it suitable for applications rangingfrom biomedical implants to engine components. The properties of DLC thin films aredetermined by the bonding configuration (sp3/sp2 fraction) of its carbon atoms. LÄS MER

  5. 9. A study on the effects of the process parameters of polymerised HMDSO using RF-PECVD in corrosion protection applications

    Master-uppsats, Linköpings universitet/Tunnfilmsfysik

    Författare :Madeleine Ardic; Anton Gifvars; [2017]
    Nyckelord :;

    Sammanfattning : In this master thesis the effects of the process parameters of pp-HMDSO were studied in the application of corrosion protection of an Al surface. The method for polymerising the HMDSO vapour was RF-PECVD. LÄS MER

  7. 10. Synthesis of hydrogenated amorphous carbon (a-C:H) thin films by HiPIMS-based processes

    Master-uppsats, Plasma och beläggningsfysik; Tekniska högskolan

    Författare :Mohsin Raza; [2012]
    Nyckelord :HiPIMS; DCMS; hybrid HiPIMS-DCMS; magnetron sputtering; reactive sputtering.;

    Sammanfattning : This thesis explores the feasibility of high power impulse magnetron sputtering (HiPIMS) to synthesize hydrogenated amorphous carbon (a-C:H) thin films in Ar-hydrocarbon ambient and the relationship between process parameters, gas phase composition and film properties. To this purpose a stable process based on HiPIMS and direct current magnetron sputtering (DCMS) has been developed. LÄS MER
