  1. 21. Geologiska och hydrogeologiska tolkningar av SkyTEM-data från Vombsänkan, Sjöbo kommun, Skåne

    Kandidat-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Love Lindberg Skutsjö; [2021]
    Nyckelord :Ilstorp; SkyTEM; grundvatten; grundvattenmagasin; geofysik; hydrogeologi; akvifer; GeoScene3D; Earth and Environmental Sciences;

    Sammanfattning : SkyTEM, an airborne TEM (transient electromagnetic method), has been used to measure the resistivity of ground in and around the groundwater reservoir Ilstorp in Sjöbo municipality, Skåne, Sweden. The results of the measurements have been analysed in an effort to increase the knowledge about the geological and hydrogeological conditions of the reservoir. LÄS MER

  3. 22. Homebuilt reactor design and atomic layer deposition of metal oxide thin films

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

    Författare :Pamburayi Mpofu; [2021]
    Nyckelord :Thin films; atomic layer deposition;

    Sammanfattning : This research thesis covers work done on building an atomic layer deposition (ALD) reactor followed by the development and optimization of an ALD process for indium oxide thin films on crystalline silicon substrates from new precursors using this new homebuilt cost-effective tool. This work describes the design, building and testing of the ALD system using an indium triazenide precursor and water in a novel precursor combination. LÄS MER

  4. 23. Direct Sampling of the Pulsed Eddy Current Response From Non-Ferromagnetic Metals

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Sara Holmér; [2021]
    Nyckelord :;

    Sammanfattning : The non-destructive testing method Pulsed Eddy Current, or PEC, can be used to measure the thickness and resistivity of conducting and non-ferromagnetic materials. In this project I investigated if a gauge at ABB, which uses PEC technology to measure the thickness of aluminium strips in rolling mills, can extract more information about the strip by sampling the direct signal with a higher resolution than before.

  5. 24. Inversion of SkyTEM Data Based on Geophysical Logging Results for Groundwater Exploration in Örebro, Sweden

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Geovetenskap och miljöteknik

    Författare :Andrée Kindlund; [2021]
    Nyckelord :SkyTEM; hydrogeophysics; geophysical logging; A priori; groundwater exploration;

    Sammanfattning : Declining groundwater tables threatens several municipalities in Sweden which drinking water is collected from. To ensure a sound drinking water supply, the Geological Survey of Sweden has initiated a groundwater exploration plan. LÄS MER

  7. 25. Intermediate layer contacts for tandem solar cells based on ALD SnO2

    Master-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Georgia Iona; [2021]
    Nyckelord :Ald; SnO2; tandem cell; solar cell; IML; intermediate layer;

    Sammanfattning : In this project, samples with a metal/semiconductor/metal structure were fabricated and investigated with the potential application as the interconnecting layer of a tandem solar cell in mind. Degenerately doped p-Si and n-Si were used as bottom (metal like) contacts, as Si represents one of the most common materials for the bottom cell of tandem devices. LÄS MER
