  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. Heteroepitaxial Growth of GaN Film on Si substrate by Magnetron Sputtering

    Master-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi

    Författare :Zahra Mohammadianrasnani; [2023]
    Nyckelord :GaN; Sputter epitaxy; Thin film;

    Sammanfattning : In this study, the effect of AlN buffer layer structure and morphology on the GaN films deposited on Si (111) substrate by reactive DC magnetron sputtering have been studied. For structural and morphological characterization X-ray diffraction (XRD) and Scanning electron microscope (SEM) were used. LÄS MER

  4. 3. Improving polarizing neutron optics by introducing 11B4C as interlayers

    Master-uppsats, Linköpings universitet/Tunnfilmsfysik

    Författare :Martin Falk; [2023]
    Nyckelord :Thin film multilayers; Neutron optics; Neutron polarization;

    Sammanfattning : In this report, the effects of adding 11B4C as interlayers into Fe/Si multilayers is studied. Fe/Si multilayers are commonly used for neutron polarization at large research facilities, and improving the polarizing properties would improve their efficiency. LÄS MER

  5. 4. Synthesis and thermoelectric properties of Cr1-xMexN (Me = Mo, V)

    Master-uppsats, Linköpings universitet/Tunnfilmsfysik

    Författare :Victor Rutberg; [2022]
    Nyckelord :Chromium nitride; thin films; thermoelectrics; physical vapour deposition; medium entropy alloy;

    Sammanfattning : Among emerging materials systems for thermoelectric applications, the early transition-metal nitrides based on ScN and CrN show unexpectedly promising properties. These properties are determined by high Seebeck coefficient, low thermal conductivity, and high electrical conductivity. LÄS MER

  7. 5. Magnetron Sputter Epitaxy of High-quality GaNand Plasma Characterization of the Process : Degree Project–Master’s Thesis

    Master-uppsats, Linköpings universitet/Tunnfilmsfysik

    Författare :Yi-Ling Lo; [2021]
    Nyckelord :GaN; Semiconductors; Nanomaterials; Thin film; Magnetron Sputtering; Epitaxy; XRD; Physical Vapor Deposition;

    Sammanfattning : Several sputtering depositions were done by direct current (DC) magnetron sputtering epitaxy (MSE) techniquefor the goal of improving the growth rate and crystalline quality of GaN thin film on Al2O3 substrate. Thegrowth rate was higher when substrate-to-target distance D = 7 cm compared with D = 9. LÄS MER
