  1. 1. A comparative study of ZnO i-layer deposited with ALD and PVD for CIGS solar cells

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

    Författare :Joel Johansson Byberg; [2019]
    Nyckelord :CIGS; ZnO; ZnMgO; solar cells; thin film; zinc oxide; window layer; ALD; PVD;

    Sammanfattning : Two identified setbacks for CIGS based devices in order to obtain higher efficiency are parasitic absorption in the window layer structure and losses in open-circuit voltage due to bad interfaces. This study investigated how the performance of the solar cell is affected by depositing intrinsic ZnO (i-ZnO) and ZnMgO with atomic layer deposition (ALD) instead of the conventional sputtering.

  2. 2. Manipulation of thin metal film growth on weakly-interacting substrates using gaseous surfactants

    Master-uppsats, Linköpings universitet/Nanodesign

    Författare :Martin Konpan; [2019]
    Nyckelord :Surface physics; material science;

    Sammanfattning : Thin films are structures with thicknesses ranging from the atomic scale to the mesoscale that are used to alter the properties of a surface and/or serve as functional layers in devices. Thin metal films deposited from the vapor phase on weakly-interacting substrates, including oxides (TiO2, ZnO, SiO2 etc. LÄS MER

  3. 3. Transparent conductive oxides deposited by magnetron sputtering: synthesis and characterization

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

    Författare :Mathias Axelsson; [2019]
    Nyckelord :TCO; AZO; solar cell; magnetron sputtering;

    Sammanfattning : The thesis has dealt with transparent conducting oxide (TCO) materials, with a focus on Al:ZnO and with studies on Sn:In2O3 and ZnO. TCOs are a material group that is used for its properties of being conductive and at the same time transparent. LÄS MER

  4. 4. Investigation of magnetic order in nickel-5d transition metal systems

    Master-uppsats, Uppsala universitet/Molekyl- och kondenserade materiens fysik

    Författare :Konstantinos Papadopoulos; [2019]
    Nyckelord :muSR; muons; skyrmions; magnetism; transition; spin; rotation; relaxation; resonance; thin; films; transition; metals; MBE; sputtering; XRR; reflectivity; molecular; beam; epitaxy; x; ray; TRIUMF; double; perovskite; longitudinal; transverse; nickel; Ni; asymmetry; positron; depolarization; chiral; lattice; helical; DM; interaction;

    Sammanfattning : Double perovskite materials exhibit alterations in magnetic order through manipulation oftheir crystal structure. Certain ultra thin metallic bilayers can create an exotic magnetic stateof confined spin textures called skyrmions. In both cases, new atomic arrangements leadto new electrical and magnetic properties. LÄS MER

  5. 5. Growth and Characterization of CrB2/TiB2 Superlattices by Magnetron Sputtering

    Master-uppsats, Linköpings universitet/Tunnfilmsfysik

    Författare :Samira Dorri; [2019]
    Nyckelord :Thin films; diborides; superlattices; reflectivity; transition-metal diborides; CrB2; TiB2;

    Sammanfattning : In the present work, growth and structural characterization of CrB2/TiB2superlattices on (0001) Al2O3substrateis studied. The superlattices are grown using a direct current magnetron sputtering (DCMS) system with a base pressure of <9E-7 Torr. LÄS MER
